Even the thyroid cancers in people who lived near the reactor were attributed to low iodine in the Russian diet -- and consequently had no effect on the cancer rate.
Let's start with this one. Total crappola...
Radioactive iodine (I-131) is a major product of uranium fission in nuclear reactors. It undergoes beta decay (gives off a very high speed electron), with a half-life of about eight days, becoming xenon-131. Iodine-131 is one of the most carcinogenic nuclear fission products.
Iodine-127 is the normal, stable isotope of iodine.
Iodine is taken up by the thyroid gland where it is an essential part of the thyroid hormones thyroxine (T4) and triiodothyronine (T3).
If someone's diet is low in iodine, absorbed iodine is incorporated and used to make thyroid hormones. The thyroid can't chemically tell the difference between stable I-127 and highly carcinogenic I-131.
If one's diet is adequate in iodine or if additional iodine is consumed prior to exposure to I-131, the thyroid doesn't need any additional iodine and very little iodine (stable or radioactive) will be absorbed and stored by the thyroid gland. It simply passes through.
So, if the people around Chernobyl were iodine deficient, they would have absorbed the highly carcinogenic I-131 in their thyroid glands where it would cause many cases of thyroid cancer (which it did).
For Coulter to say that the spike in thyroid cancer in people around Chernobyl was due to dietary deficiency and not the carcinogenic I-131 from the reactor disaster is typical Coulter bullshit.
As for...
Amazingly, even the Soviet-engineered disaster at Chernobyl in 1986 can be directly blamed for the deaths of no more than the 31 people inside the plant who died in the explosion.
...makes perfect sense if you define all the deaths due to radiation expose, such as in the people who responded and dealt with the disaster...as being indirectly due to the reactor disaster.
Ann Coulter is a great conservative gadfly. When it comes to science she's a moron.
You just made her point in your post....I am quoting your post here...
"If someone's diet is low in iodine, absorbed iodine is incorporated and used to make thyroid hormones. The thyroid can't chemically tell the difference between stable I-127 and highly carcinogenic I-131."
Now stay with me here...why did their bodies absorb the carcinogenic iodine? Well unless I am mistaken, it is because they had an iodine deficiency. You said as much yourself.
So in an otherwise healthy individual, the effect would have been negligible at worst. Because they were iodine deficient, their bodies were affected by the radiation.
I don't see where she is wrong.
