They said seven people who were exposed to radiation at close range received doses too small to cause harm.
In research studies, subjects have received doses ranging from 75 milligrams a day to 1,200 milligrams a day.
But by the end of March, "approximately 100 workers had received doses greater than 10 rem," the chronology said.
More than 5,000 workers received doses of as much as one sievert within a few hours, Professor Wakeford says, and some 30,000 clean-up workers received doses of more than 250 millisieverts in the following years.None of this makes Fukushima trivial; it is a grave crisis.
Subjects received doses of 10, 20, and 40 g of lactose [65].
Specifically, previously irradiated head and neck patients may have received doses close to the tolerance limit to their brainstem and spinal cord.
The radiation dosimetry estimates obtained from Formosa rock monkeys suggest that the received doses of most organs range between 8.3 and 39.1 μGy/MBq.
The amount of radiation involved was small (the two most exposed workers received doses of about 1.7 millisieverts, equivalent to a high-dose medical x-ray).
However, many patients received doses that were too small and have relapsed, says George Bigelow, a psychologist at Johns Hopkins University.
Thirty-five Wistaratsts (Rattus norwegicus) were divided into five groups (a normal diet group, a hypercholesterol diet group, and hypercholesterol groups that received doses of 50 mg/kg, 150 mg/kg, and 300 mg/kg body weight PsP).
Twenty-one percent of our trauma alerts and stats received doses within this range for a single trauma evaluation which is a very important baseline determination for future epidemiologic analysis.
