Iodine 131 was measured from dried sewage sludge by Chiba prefectural government again. Iodine 131 is the nuclide to cause thyroid cancer or thyroid related disease. You are to take Iodine table after nuclear accident but now it’s already too late.
The half life time of iodine 131 is only 8 days, and it is produced from nuclear fission. It makes us question, “Has nuclear fission really ended in Fukushima?”
Iodine 131 is also used for medical treatment, but high level of Iodine 131 has been measured from various places. We need to verify where it keeps coming from.
(cf. 4,800 Bq/Kg of iodine 131 was measured in Tokyo
570 Bq/Kg of Iodine 131 was measured in Gunma
