Individual Radiation Exposure Dose Due to Support Activities at Safe Shelters in Fukushima Prefecture, Hirosaki University Study, Published November 16, 2011:
[...] Hirosaki University, just after the first phreatic explosion, sent many of its staff members to the safe shelters that were set temporarily for the residents of the area around the nuclear power station, to support the radiation survey and monitor the contamination of the safe shelters. [...]
The contributions of Te-132, I-131, Cs-137, Cs-134, and I-132 show increased values when approaching the Fukushima Dai-ichi Nuclear Power Station from Osaki, Miyagi Pref. [...]

The Nuclear Regulatory Commission and US Department of Energy supported a study that tested the ‘effectiveness’ of iodine-132 compared to iodine-131 (Emphasis Added):
Description: The thyroidal effects of short-lived radioiodines such as 132I, 133I and 135I are not well defined. Upon release from nuclear reactors these radioiodines pose potential risk to human health. The effects of 132I and 131I were compared. The same effect was found in goitrogen-stimulated rat thyroid glands (in terms of 50% suppression of thyroid gland wt increase) at injected activities of 93 .mu.Ci 132I and 13 .mu.Ci 131I. Doses were 3 rad/.mu.Ci 132I and 194 rad/.mu.Ci 131I. The same 50% suppression for thyroid dose occurred at about 280 rad from 132I and 2500 rad from 131I, suggesting an approximately 9-fold increase in radiologic effectiveness of 132I over 131I.
