The below news item will obviously stir up emotions, especially for the poor members of the public in and around the Fukushima Prefecture. As is often the case, there is no data provided, such as:
1. What is the dose that was exceeded, is it the 250 mSv?
2. External, internal or mostly from contamination?
3. Was the latest dose an acute exposure or dynamic, over time?
4. The workers feel fine. That's good, but when did they receive the exposure? 250 mSv wouldn't really cause any significant effect any way.
5. What tests are they going to run? White blood cell counts drop even with a cold. Would be of interest to know what type of studies are planned in this sort of circumstance.
TOKYO (AP) May 30 -- Two workers at Japan's crippled nuclear plant might have exceeded a radiation exposure limit amid concerns about the risks faced by the workers struggling to contain the crisis.
Tokyo Electric Power Co. said Monday the two control room operators are being tested further and don't have immediate health problems.
If exposures beyond the limit are confirmed, they would be the first men to reach the government-set limit.
The government had eased its previous limit for men soon after the earthquake and tsunami set off the crisis at the tsunami-hit Fukushima Dai-ichi plant on March 11.
The two men were responsible for Unit 3 and 4 central control rooms when the quake and tsunami knocked out the plant's power and cooling functions.
