Abstract: A large amount of radioiodine isotopes (mainly (131)I, t(1/2) = 8 days) was released from the accident at Chernobyl Nuclear Power Plant (CNPP) in April-May 1986. An increase in childhood-thyroid cancer in the contaminated areas in Belarus, Russia and the Ukraine was demonstrated to be caused by radioiodine released at the time of the accident. However, there is a lack of quantitative data on the (131)I levels in the local environment (e.g. air, plant, soil). At this point, a long-lived iodine isotope, (129)I (t(1/2) = 15.7 million years), also released with a certain ratio to (131)I from CNPP, could be used for estimating the (131)I levels in the environment.
