Risk assessment request
Thank you all so much!
I really don't feel background gamma exposure from a commuter flght is helpful for an infant ingesting beta particles. Babies don't eat and drink airplanes. Not all radionuclides are equal in behavior and the exposure pathway matters.
In the "safe dose" consumer thresholds below the data, it would be helpful to have the infant PAG/DIL provided by the FDA. We're not all 30 year old men from studies 20 and 40 years ago and our risks are not the same as a female child's.

*plus, the conversions for an infant are killing me, I just want to keep the babies safe :).
Hi Joseph
With respects to the DIL you posted, why does the SR-90 drop to 160 Bq/kg for a 15 year old? There also seems to be a similar pattern for other radionuclides concerning a 15 year old, why is that? Does it mean they are more susceptible at that age?
Thank you Joseph
I look forward to your response.
Can you clarify this? Isn't the level of concern a TOTAL dose?
at which intervention is recomended?
In other words of a child drank about 10 litres of milk a week, for example, at the highest dose of .7 Bq/li that would be 7 Bq/Li week of exposure to I 131 and the maximum dose before protective intervention would be in 7 weeks.
If the dose stays high of radioiodine then infants would max out in a matter of months (indicating that the standard sees this as a serious risk requiring intervention to reduce it.
That said it seems prudent to limit ANY exposures.
or am I way off here?
First of all, thank you Joseph
That doesn't address multiple source low dose pathway exposure for infants. An infant is not encountering only milk exposure, but even so you've discounted a substantial radiological supralinear dose-response, meaning the greatest per-dose risks are at the lowest doses. Findings document that the very young are especially susceptible to adverse effects of radiation exposure, even at relatively low doses.
Even studies for targeted, controlled radiation in children give a maximum dose since they found lower doses actually increase cancer in children that higher range therapies did not.
I'm just saying the consumation examples you're providing are potentially misleading in risk chracterization and do not apply to children. The lack of cross-disciplinary approach in those numbers provided would be better augmented, disclaimed or left out entirely.
I just feel our nursing mums
I just feel our nursing mums and parents should openly understand their infant's risks are substantially greater as they make choices:

That document was confusing
That document was confusing to me an average mom. I do not feel my baby is at enough of a risk to switch to formula. How can I use that article in a practical application to my family?
We live in the Bay and eat organic and drink Almond or Hemp milk.
Hello, Thank you for
Hello,
Thank you for responding in a kind and understanding manner. I am trying to keep informed on the issues to ensure I do the right things for my baby. However I am not a scientist so many of the threads on here are beyond me. I appreciate the information that your team has come up with and have read the FAQ which I found to be a bit more understandable than many of these threads. Keep up the good work folks.
Thanks
