RERF admitted radiation may cause deaths due to non-cancer disease

Radiation Effects Research Foundation (A cooperative Japan-US research organization) secretly published the report about deaths due to non-cancer disease caused by radiation on 9/30/2011.


Deaths due to non-cancer disease
Analyses of the Life Span Study (LSS) mortality data (1950-1997) show a statistically significant dose-response pattern for death from diseases other than cancer. The excess does not seem limited to any particular disease. Among the 49,114 LSS survivors with colon doses of at least 0.005 Gy (DS86), 18,049 non-cancer deaths occurred (excluding deaths attributed to diseases of the blood). Circulatory diseases account for nearly 60% of these deaths, with digestive diseases, including liver diseases, and respiratory diseases accounting for about 15% and 10%, respectively.

Aside from diseases of the blood, the number of excess non-cancer deaths associated with A-bomb exposure is estimated at 150 to 300 cases. The death rate following exposure to 0.2 Gy (the mean radiation dose for the 49,114 survivors with doses >0.005 Gy) is increased by about 3% over normal rates. This is less than the death rate increase for solid cancers, where corresponding increases are 7% in men and 12% in women (age 30 ATB). The dose-response pattern is still quite uncertain (Figure 1).

A significant radiation dose-response pattern was also seen for non-cancer blood diseases. Such diseases were studied separately since they may represent various hematologic malignant or premalignant conditions. Among the 128 deaths for which medical records were available and in which hematologic reviews were performed, about 45% were clearly classified as non-neoplastic blood diseases, 6% were diagnosed as leukemia or other hematopoietic cancers, and the remainder were potentially preneoplastic.

In the absence of known biological mechanisms, it is important to consider whether these results might be due to biases or to diagnostic misclassification of cancer deaths. Investigations have suggested that neither of these factors can fully explain the findings, especially for circulatory diseases that have been investigated more fully.

The Adult Health Study (AHS) incidence studies of non-cancer diseases show relationships with A-bomb dose for benign uterine tumors, thyroid disease (e.g., thyroid nodules), chronic liver disease, cataract, and hypertension (Figure 2). The LSS mortality data also show dose-related excesses for respiratory diseases, stroke, and heart diseases (Figure 3).

heart disease mortality suggest that radiation is associated with hypertensive and congestive heart disease

Although the LSS data on heart disease mortality suggest that radiation is associated mainly with hypertensive and congestive heart disease, AHS data also suggest an association with myocardial infarction, as well as with a measure of atherosclerosis (aortic arch calcification). There is particular evidence, therefore, from both AHS clinical data and LSS mortality studies, that the rates of cardiovascular disease are increased in A-bomb survivors, especially, it appears, for persons exposed at young ages. Studies regarding possible underlying biological mechanisms are being conducted.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
