Abstract ---Chronic radiation syndrome
is based upon victims who were exposed to radiation for at least
3 years and who had received at least 100 rem or more to the marrow.
The report reconfirms the International Commission on Radiological
Protection (ICRP) recommendation that the maximum value of the dose
constraint to be used in the optimization of radiological protection
for a single source should be less than l mSv in a year, and that
a value of no more than about 0.3 mSv in a year would be appropriate.
Chronic exposure of radiation, who developed chronic radiation sickness,
leukopenia, thrombocytopenia and inhibition of non-specific immunity
factors, slight increase in nodule prevalence and thyroid antibody-positive
subjects, increased frequency of chromosomal aberrations (both stable
and unstable types) and CD3 – CD4+ mutant T-lymphocytes in the peripheral
blood. Studies show that radioactivity from nuclear plants is getting
into the environment and human body, and there is now strong evidence
that it is hurting the health of Americans. There is now substantial
evidence that exposure to radioactive releases from nuclear reactors
is a significant causal factor of increasing childhood cancer rates
and of other adverse health effects. |
