Links to information on radioactivity in sewage In a wastewater treatment plant (WWTP) in Kohriyama, Fukushima, high radioactivity sludge was found, 26,400 Bq/kg in sewage sludge, and 334,000 Bq/kg in molten slag, which is more than 1,000 times of 246 Bq/kg in molten slag before the nuclear plant accident. The followings are some information on radioactivity in sewage sludge on the web. Most of them are from the USA in the 1990s. 01.
