1,000 Microseiverts is considered the maximum safe exposure dosage for one year. An Airline pilot will be exposed to an average of 85 microsieverts flying between Honolulu and Tokyo.
So, if the numbers from TEP are to be believed, the exposure dosage on site has gone from 1,000ms, to just over 1,900.
A CT Scanner runs about 2000-2200 micro sieverts in one use.
Not a really dangerous dosage, but not one you want to be exposed to over a long period.
To put this in perspective, the firefighters at Chernobyl got about 7-13 MILLION microsieverts, and a cancer patient gets around a 50-60 MILLION microsievert dose to the affected area.
Do you recall what those guys who went to the edge at Chernobyl got? I remember a documentary once that had one of the ones that got a lethal does talking about not fearing what he can’t see. It was really sad. He didn’t last very long.
The Thyroid Cancer Hoax
In its final conclusions on the health effects of the Chernobyl accident, the UNSCEAR report stated the following:"The number of thyroid cancers (about 1,800) in individuals exposed in childhood, in particular in the severely contaminated areas of the three affected countries, is considerably greater than expected based on previous knowledge. The high incidence and the short induction period are unusual. Other factors may be influencing the risk."
One of these factors are what are called "occult" thyroid cancers, those detected at autopsies by histological studies, and which do not cause visible clinical disturbances during the person's lifetime. These occult thyroid cancers occur en masse all over the world. For example, in Canada their incidence is 6,000 per 100,000 population; in Poland it is 9,000; in the United States 13,000; and in Finland 35,000. The highest incidence of thyroid cancers in children found in Russia, before the Chernobyl accident, was 26.6 per 100,000; in Belarus, 17.9; and in Ukraine, 4.9. Thus, the potential for the discovery of "excess" thyroid cancers, after the intense health screening that took place after the accident, is enormous.
According to UNSCEAR data, the increase in thyroid cancers diagnosed in children under 15 years old, began to be seen as early as 1987 in Russia, and in 1990 in Belarusthat is, only one year and four years after the accident. However, the latency time for radiation-induced solid cancers, such as thyroid cancer, is about 10 years. According the data presented in the UNSCEAR 2000 report, there is no relationship (or rather there is an inverse one) between the registered incidence of thyroid cancers in children, and thyroid radiation doses to the population in contaminated areas (Figure 1).
Figure 1 MAXIMUM THYROID CANCER INCIDENCE RATES IN CHILDREN IN HIGHLY CONTAMINATED REGIONS, COMPARED WITH RADIATION DOSE Shown are the maximum thyroid cancer incidence rates in children in highly contaminated regions of Belarus, Russia, and Ukraine, who were under 15 years old at the time of diagnosis, compared with average thyroid radiation doses. As can be seen, the area with the lowest radiation dose has the highest incidence of thyroid cancer.
Thyroid cancers are 90 percent curable. As of this writing, only one of these children has died.
