Some of the very brave workers who went through the worst period of time when the radiation level was fairly high will likely suffer some long term health challenges.
I have only seen one confirmed report of a worker who exceeded the normal safety limit for nuclear technical workers. The level was still below that which is determined to increase cancer risk and well below the level necessary to create any symptoms of radation exposure.
There have been reports of radiation spikes that were high enough to cause exposure risk, but no workers were in the exposure area at the time of the spikes. The normal limits for yearly exposure have been kept in place and monitored for each employee. The employees are to be lauded for standing posts in a high risk environment, but to this point, none of them has assumed the role of martyr.
Heroes in the truest sense of the world.
Excellent news that there are no fatalities.
