CLINICAL EFFECTS ARISING FROM RAPID WHOLE-BODY DOSES OF IMMEDIATE
GAMMA RADIATIN OR THE SAME AMOUNT OF RADIATION ACQUIRED IN THE
COURSE OF ONE HOUR
The body can handle and repair a certian amount of free radical damage
whether it is caused by radiation, drinking alcholol, heavy labor, heavy
exercise, eating slightly rancid food, or from wounds. The following
table shows this ability of the body to repair itself to a limited
extent.
| Medical care needed |
Accumulated Radiation Exposures (R) over
a period of |
|---|
| |
One week |
One month |
Four months |
|---|
| None, no deaths | 150 R |
200 R | 300 R |
| Some, 5% may die | 250 R |
350 R | 500 R |
| Most, 50% may die | 450 R |
600 R |
The above chart is from Richard C. Oster Sr.'s article in Journal
of Civil Defense, Oct 1987, "Fallout Radiation: Levels and Effects".
Note that the a 500R exposure over 4 months causes 5% deaths whereas
the same exposure over 1 hour causes 50+% deaths.
The reason for the variance of outcome in exposure RATES is that
radiation of the type that we are talking of is ionizing radiation.
Ionizing radiation causes the formation of free radicals in the body.
Radiation sickness is a free radical disease just as a hang-over is.
The body can handle a certian amount of free radicals before the free
radicals overwhelm the body's free radical scavenging system. When
overwhelmed, part of the free radical damage consists of damage to the
body's free radical scavenging system creating a vicious cycle. The
body's ability to scavenge free radicals may be improved by a factor of
three using arious vitamins and minerals (see the three books,LIFE
EXTENSION - A PARTICAL SCIENTIFIC APPROACH, THE LIFE EXTENSION
COMPANION, THE LIFE EXTENSION WEIGHT LOSS PROGRAM by Durk Pearson &
Sandy Shaw).
The reason for the vairiance of outcome from exposure DOSES is that
there is a wide variance in people's ability to handle free radicals.
This is based on genetics, age, state of physical conditioning, overall
health, and quality of nutrition.
