The CTBTO isotope measurement station at Takasaki, Japan (Japanese) is indicating radioactive iodine-131, barium-140 and tellurium-132 was being detected every day from Oct.1 – Oct.31. Previous reports (link here) show that officially, iodine has not been detected since July 2011, barium since May 2011, and tellurium since April 2011. Of course, iodine-131 has regularly been showing up in sewage sludge, as reported here and at Fukushima Diary. And Mochizuki is reporting that radioactivity in seawater has been increasing from early September to mid-October.
Tellurium-132 is produced by criticalities. It was the first isotope detected after the Japan earthquake, and it indicated that a meltdown was occurring. It decays into iodine-132. It is currently appearing at mid-April 2011 levels.
Barium-140 is a dangerous isotope. Its presence always means strontium-90 is also present, because both isotopes are released by the same physical process. It is being released at May 2011 levels.
Iodine-131 causes thyroid cancer and many other thyroid diseases. It was discussed earlier in this blog that 31 times as much (more dangerous) iodine-129 was being released than I-131. It is being released at June 2011 levels.
I had reported earlier in this comment on Sept. 24 that everyone without iodine sensitivity or allergy should start taking stable iodine. In this post on Oct. 24 I mentioned that I had started taking Lugol’s iodine on a daily basis. Looks like my canaryhood has been verified.
