 · Radioactive iodine (131 I) and cesium (134 Cs and 137 Cs) were detected in drinking water after the explosion (WSD, HSB, MHLW, 2011; Ikemoto and Magara, 2011). Several groups have investigated the occurrence of 131 I, 134 Cs, and 137 Cs at water purifiion plants ( Goossens et al., 1989 ; Esumi et al., 1986 ; Gäfvert et al., 2002 ; Kamata et al., 1973 ) although data after nuclear .

WATER CONTAMINATION IMPACTS ON THE WEST COAST

Radioactive Cesium (Cs137) is the primary isotope of concern and Cs 137 levels right near the Fukushima Daiichi NPS have generally been below 10 Bq/L since the contamination was detected last year [3]. Since this is considered safe for drinking water, and combined with monitoring

This study examines the activity of Cesium 137 radiation in air filters and Personal Protective Gear (PPG) worn by remediation workers in and near the Fukushima exclusion zone. Activity is evaluated after radioactive decays are counted using a BroadEnergy Germanium (BEGe) detector, over a constant period of time for each PPG sample.

The present author studied associations between radioactive cesium (137Cs) and increases in PC. There is a correlation between the geographical map of the incidence of and mortality from PC and the map of nuclear plants, related nuclear accidents and nuclear tests with consequent radioactive fallout, of which 137Cs, with its halflife of about 30 years, is one of the most relevant components.
