Can Cesium in grass attach to kids playing soccer?
thanks for the data.
Can Cesium in grass attach to kids playing soccer?
on a different note, have you guys been able to create a correlation coefficient matrix for estimated release of particulate in japan and then ensuing contamination in the bay area?
keep up the good work!
Tokyo Children Harvesting HOT Tea
Tokyo Children Harvesting HOT Tea
Radioactive cesium detected in tea leaves grown in Tokyo
http://mdn.mainichi.jp/mdnnews/news/20110701p2a00m0na005000c.html
Radioactive cesium was detected in processed tea that was made from leaves that elementary school children picked in Tokyo as part of their school curriculum.
The Itabashi Ward Office announced on June 30 that 2,700 becquerels of radioactive cesium -- in excess of the government's provisional limit -- was detected in processed tea that used leaves picked at a plantation in the ward by some 300 students of local elementary schools.
According to the ward office, the tea-picking class took place on May 9, and fourth- and fifth-grade students from three public elementary schools in the ward participated in the event. When the approximately 20 kilograms of processed tea -- made of some 80 kilograms of first-harvest leaves that the students had picked -- was screened, 1,300 becquerels of cesium 134 per kilogram and 1,400 becquerels of cesium 137 per kilogram were detected.
Drinking HOT tea is hazardous
The primary threat to these Japanese children, would arise from drinking the tea they harvested. It is not clear that they did drink any of this tea. Nor is it clear if the Cesium was measured in fresh or dried tea leaves. The drying process doubles the Bq/kG radiation values.
It is unknown, if the kids wore gloves, washed their hands, sustained any cuts, ate any tea leaves, licked their fingers or wore particulate face masks. Notwithstanding all these open questions, the primary danger is drinking the tea, not in picking it.
This was a farming demonstration, and did not endanger the children as much as the round-trip bus trip from school.
Be wary of repercussions of landscaping/ weedeating/ mowing
Kids and the elderly and sick should probably be cautious around weedeating or mowing. When the grass is shredded and becomes airborne that is a concern for inhalation/ingestion.
That's good information to share if you know someone who is a landscaper or mows yards etc...filtration masks etc are a small step which can be taken.
Worry about something else
The short answer is yes. (but)
Yes, kids playing in the grass, rain and snow will collect trace levels of radionuclides on their bodies and clothes. And yes, some tiny fraction of those trace deposits are absorbed through the skin and because of all the other things that kids do.
This has caused a lot of very sick children in Japan. It was a minor player in the USA for the approximate 60 day time slot of March 19 through May 18.
Hopefully by now, the grass has been cut (and bagged) several times. Hopefully by now, the grass has been watered several times, (which soaks far more radionuclides deep into the soil than into the grass).
Bag the grass and leaves in 2011 and do not mulch. Oh and 2012 is 'iffy', unless you had NO 2011 spring rains (drought conditions).
Children play in the grass, unlike cattle and goats, who eat it. Just wash the sports clothes more often this summer. Oh, and...

A 3 year Adult Internal exposures in 2 Months, would approach a 30 year childs dose. However, childhood does not LAST 30 years. This 'kinda-sorta' sounds like a countable infinity situation.
So, children, DON’T eat your vegetables!
http://www3.nhk.or.jp/daily/english/24_02.html
A group of doctors has found that the estimated level of accumulated internal radiation exposure for people living in Fukushima Prefecture has exceeded 3 millisieverts. The researchers, including doctors who have provided medical care to A-bomb survivors, conducted analysis on the food and urine of 15 residents in Iitate Village and Kawamata Town in Fukushima Prefecture. These areas are about 40 kilometers from the Fukushima Daiichi nuclear power plant.
They estimate that residents have been internally exposed to up to 3.2 millisieverts for about 2 months, measuring from the date of the accident in March until early May. Three millisieverts is 3 times higher than the long-term annual limit for ordinary people recommended by the International Commission on Radiological Protection. One of the researchers, Nanao Kamada, says people should refrain from eating vegetables grown in the area where high levels of radiation have been detected.

Considering there are no
Considering there are no kids with symptoms anywhere in that article, and that we are talking about the most contaminated area outside of the evacuation zone in Fukushima (Iitatemura), this would seem to indicate that the "30 years child dose" you are talking about is still safe in the short run? And how about the US in general compared to that area?
Let's not forget your comment:
"This has caused a lot of very sick children in Japan. It was a minor player in the USA for the approximate 60 day time slot of March 19 through May 18. "
Were are the sick children of Japan you referred to? Were you trying to support your claim with that article?
Planet YOU

On Planet YOU!
Yes, I am attempting to indicate documentable support for my contention above, But not to you.
Doubtless the patients and relatives are more concerned about these dosages, than you are.
Most rational persons would concur that children are people. Perhaps you disagree.
It is generally accepted that the sensitivity of children to radiation exposure is about an order of magnitude. Perhaps that premise is rejected, on Planet YOU. Suit yourself.
Have a nice day... loser!

Sorry, I thought you were
Sorry, I thought you were Bill Duff. I'm very concerned about children getting sick, but let's try to gather some data and know what we are talking about before repeating false rumors. And specially, let's try to analyze where the data are coming from and how can we compare it with the situation in the US before addressing a concerned parent.

Another battery of 100% positive urine tests in Fukushima
Radioactive substances were found in urine samples of all of 10 surveyed children from Fukushima Prefecture in May.
http://mdn.mainichi.jp/mdnnews/national/news/20110630p2g00m0dm106000c.html
According to the urine test, 1.13 Becquerels of radioactive cesium-134 per 1 liter of urine, the largest amount for the isotope among the 10 surveyed children, was found from an 8-year-old girl, while the largest amount of cesium-137 at 1.30 Becquerels was found in a 7-year-old boy.
David Boilley, president of the French nongovernmental organization (NGO) ACRO radioactivity measuring body, said at a press conference in Tokyo that the results of the survey on 10 boys and girls in Fukushima City aged between 6 and 16 suggest there is a high possibility that children in and near the city have been exposed to radiation internally. ACRO also investigated radiation exposure of children who resided near the site of 1986 Chernobyl nuclear disaster.

A government panel is discussing whether to compensate people suffering internal exposure to radiation from the troubled Fukushima Daiichi nuclear plant. Panel leader Yoshihisa Noumi said discussions should be made on whether to recognize such people or those exposed to radiation but yet to develop health problems as suffering mental distress. The members also discussed whether to compensate for damage caused by import bans on Japanese goods by foreign governments and a decrease in tourism to Japan.
The panel decided to compensate people for mental suffering who were forced to evacuate after the nuclear plant accident.

Far Exceeding the Evacuation Limit
"The figure was 13.9 microsieverts per hour, far exceeding the legal limit forcing the evacuation of local residents."
http://www3.nhk.or.jp/daily/english/03_15.html
Japan's new nuclear crisis minister has inspected the monitoring of radiation levels in the evacuation zone around the Fukushima Daiichi nuclear power plant. Goshi Hosono on Sunday visited Iitate Village in Fukushima Prefecture, more than 30 kilometers northwest of the troubled plant.
He saw the figure was 13.9 microsieverts per hour, far exceeding the legal limit forcing the evacuation of local residents. He asked officials to keep as accurate a record as possible for the safety of the people.

That is why a fallout is so bad.
Yes, it will for sure.
Yes, it will for sure.
What is the process?
When you skid in the grass
When you skid in the grass there is friction. The friction will crush the grass. The green liquid with some Cesium from the grass will stick to clothes and skin. This will happen for both wet and dry grass.
I am not sure how well Cesium is absorbed through the skin.
Folks, these questions are
Folks, these questions are answered about 800 times. Every single particle discussed, Cesium, Iodine, Strontium, Plutonium are all cancer causers and all can be absorbed or inhaled. We will all live them for the rest of our lives, so just deal with it. Soccer or a walk in the park, it doesn't matter anymore. We'll have to deal with long term consequences of Fukushima. That is unless you plan on moving to South America.
OR you can educate yourself. There is that.
Here is a decent start in terms of learning about getting it out once it is in: http://www.etszeolite.com/
Where are they answered?
Pay attention.
Asked two direct questions of the technical experts, who so far haven't had the time or inclination to respond. The second was regarding a Correlation Coefficient Matrix.
You are incorrect, while each may cause cancer, each one of the elements are different, have different weights, and will act differently. Haven't seen Strontium nor Plutonium reflected or reported anywhere in the US to date. Cesium has been reflected in the grass by the UCB team.
Anybody from UCB care to explain the process by which Cesium could bind to player's body?
Will it act as the person above described:
In the grass -> friction -> liquid->clothes/skin scenario?
or does it follow a different process?
CsCl skin contact hazards
Cesium Chloride (CsCl) skin contact hazards documented in Gaiania, Brazil incident.
The typical pathways for cesium are ingestion and inhalation. The Goiania, Brazil cesium contamination incident is a documented study of skin contact hazards with cesium chloride salt (a highly soluble compound).
http://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+7389
On September 13, 1987, in the city of Goiania (Brazil), two individuals found a source of ionizing radiation used for medical teletherapy that contained 50.9 TBq (1375 Ci) of cesium-137, which had been abandoned in the interior of an empty building where a radiotherapy clinic had been functioning. They removed the rotating assembly of the shielding head of the medical teletherapy unit containing the radioactive source and brought it to the house of one of them. There, they violated the shielding and ruptured the source canister... . Part of the rotating shielding assembly containing the damaged source was sold to a scrap yard owner, who brought it home because he admired the blue glow that appeared in the dark. Small fragments of the source were distributed among relatives and friends. Some of them rubbed the material on their skin to appreciate its brightness. The accident was aggravated during the 16 days that elapsed between the rupture of the source and notification of competent authority. The source, in the form of cesium chloride salt (a highly soluble compound) and its inappropriate handling contributed to the dissemination of the cesium and, as a consequence, the contamination of many people and the urban environment. The passing of contaminated materials from one individual to another, social and professional contacts among people, the movements of animals, wind and rain were the major pathways for the dispersion of the cesium. The preliminary radiometric surveys and reports from individuals identified as having been in contact with the cesium necessitated the implementation of intervention measurements for the public and the urban environment. ... Seven areas were identified, isolated, and designated as the major foci of contamination. Of 159 houses monitored, 42 were evacuated and decontaminated, six were demolished and 53 repaired. In all, 58 different public places were decontaminated, including pavement, squares, shops, and bars, along with 64 vehicles. The emergency responses, which lasted 6 months, involved significant resources, as for example, the 730 emergency workers assigned to decontamination tasks, which generated some 3500 cu m of radioactive waste. A soccer stadium ... was chosen ... as a triage and sorting center. There, an emergency monitoring program .... consisted mainly of external skin contamination measurements .with. portable gamma radiation detectors... . Those persons who presented positive results were referred for repeated showers with water and neutral soap. The measurements performed at the stadium lasted from September 30 to December 21, 1987. A total of 112,800 persons ... out of 1 million inhabitants... were registered and surveyed... Of this total, 249 persons showed some signs of contamination.

/SIGNS AND SYMPTOMS/ /ACUTE RADIATION SYNDROME/ Approximately 250 individuals were exposed externally to an open 50.9 TBq (1,375 Ci) 137-cesium chloride radioactive source in Goiania, Brazil, in 1987. Many of these individuals also experienced oral and dermal exposure. The estimated absorbed doses ranged from 1 to 7 Gy (100 to 700 rad). The exposed individuals showed signs and symptoms of acute radiation syndrome including vomiting, diarrhea, and nausea, as well as skin lesions from radiation burns, orofacial lesions, ocular injury, hematological effects (bone marrow aplasia, leukopenia, thrombocytopenia, lymphopenia, neutropenia), mild elevations of some liver enzymes, and reduced sperm counts. Twenty individuals developed the acute radiation syndrome, 14 (70%) of whom developed bone marrow failure after having received whole-body radiation doses ranging from 1 to 7.0 Gy (100 to 700 rad). Four (29%) of these 14 individuals died. The adverse effects were the result of beta and gamma radiation, not cesium per se. /Cesium-137 chloride/

/BIOMONITORING/ /GENOTOXICITY/ Following the Goiania radiation accident, lymphocytes from 110 exposed or potentially exposed individuals were analyzed for the frequencies of chromosomal aberrations (dicentrics and centric rings) to estimate absorbed radiation dose. Dose estimates for 21 subjects exceeded 1.0 Gy, and for eight subjects they exceeded 4.0 Gy. Four of the subjects died. After the emergency period, a cytogenetic follow-up of 10 of the highest exposed patients was started. The results suggest that the average disappearance half-time of lymphocytes containing dicentric and centric rings was 130 days, which is shorter than the usually accepted value of 3 yr reported in the literature. /Cesium-137 chloride/

mutational spectrum
The mutational spectrum for the exposed population is comprised of 90 independent mutants.

/BIOMONITORING/ /GENOTOXICITY/ The current study comprises the analysis of mutations in 10 individuals accidentally exposed to cesium-137 during the 1987 radiological accident in Goiania, Brazil. Their exposures were among the highest experienced, ranging from 1 to 7 Gy. Peripheral T-lymphocyte samples were obtained 3.3 years after the original exposure and mutation was studied at the hprt locus using the 6-thioguanine-resistance selection assay. The mutational spectrum for the exposed population is comprised of 90 independent mutants. Based on T-cell receptor analysis, only 5% (5/95) were clonally related. Mutants were initially studied using RT-PCR and directly sequenced using an automated laser fluorescent DNA sequencer. Mutants that repeatedly failed to produce cDNAs were studied using a multiplex PCR assay with genomic DNA. Missense mutations were the most frequent event recovered, comprising 40% (23/57) of the spectral sample. An excess of events involving A:T base pairs was observed, exhibiting a significant difference (chi square = 12.7, P = 0.0004) when compared to the spontaneous spectrum. This finding may reflect the effect of ionizing radiation-induced damage, suggesting a potential similarity to radiation effects in prokaryotes. At the genomic level, 36.7% (33/90) of the mutants exhibited gross structural alterations, as detected by multiplex PCR. Deletion events were over-represented in our spectral sample, displaying a twofold increase when compared to the frequency observed in the spontaneous mutation database. /Cesium-137 chloride/

Joseph,
What form is the Cesium in? Is it a salt or an oxide of cesium?
Thank you
Very much appreciate your reply and look forward to seeing the correlation data.
All the best to you Joseph and the BRAWM Team!
What about Te-132, I-131,
What about Te-132, I-131, or Plutonium be absorbed through the skin?
Cesium is water soluble, so
Cesium is water soluble, so I imagine it can be absorbed by the skin.
Does wet or dry grass matter?
So if the grass is dry will the cesium still be absorbed by the skin?
Or another way of phrasing the question could be...where does the cesium in the grass reside and how does it get transported into the body?
thanks
it is ON the grass and not
it is ON the grass and not visible.
