The inspection by the government agency found 9,760 and 7,690 becquerels of iodine-131 in the thyroid glands of the workers, 10 times higher than other workers at Fukushima, reports said.
The tests sparked fears that their radiation exposure had been several hundred millisieverts, Jiji said.
A few comments. First, if they did get, say, 200 mSv from the internal exposure, you add it to external dose to get the total. Meaning they may very well have gone over 250 mSv.
But if it’s iodine, it’s not whole body exposure. They probably mean “hundreds of mSv” to the thyroid. But I doubt they scaled up the legal specific organ dose to go with the emergency whole body dose. So…over the limit, they are. (Does that sound too Yoda?)
Hopefully that’s a worse-case scenario. Remember that I-131 has an eight-day half-life, plus whatever the body eliminates. So they’re probably (oh, who knows?) assuming the men got the internal exposure early, maybe March 11th or so. If they’re reading ~10,000 Bq now, it would have been up to 1,000x more at that point.
Honestly? I don’t know how that could go undetected. Even given what we’ve seen. There’s video of them frisking workers. Well, when those guys approached a frisker it would start responding. And it would go crazy when brought near the neck. Heck, I could find that level of iodine with a dose rate meter. And they were supposedly also giving them whole body counts. There’s no way to miss it with that, either.
So, hopefully, they didn’t get it at the earliest. But even at their current levels, I could never miss that activity with a frisker. Never. You’d have to be in a background level so high, frisking is utterly useless in the first place.
And why the heck weren’t they all taking potassium iodide tablets?! Especially given the incompetent use of respirators we’ve seen repeatedly. My first guess is, that’s why these two stick out from the rest.
I just don’t know what they’re doing. As usual.
I’m guessing they didn’t get enough exposure to recommend “burning out” their thyroids. That kind of dose is probably in the multi-Sievert range. In that case, the chance of future thyroid cancer is consider large enough to give them much, much more iodine, to kill the organ.
This is the new standard in radiological incompetence. I’d say sterilize the folks making these decisions, but it’s probably a bunch of old farts. So sterilize their children and grandkids. Genes, out of the pool!
