Removal of radioactive iodine and cesium in water ...
· 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 .Get Price
Tank Closure Demonstration Project Advances at SRS
Savannah River Remediation (SRR) recently installed four new ionexchange columns into the Tank Closure Cesium Removal (TCCR) process unit. A pilot demonstration helping accelerate tank closure at SRS, TCCR selectively removes radioactive cesium from salt waste in Tank 10 in H Tank Farm. The four ionexchange columns hold a speciallyGet Price
#Radiation in Japan: Radioactive Cesium from Ashes from ...
· Not a water purifiion plant or at a waste water treatment plant, but a plant that burns regular, garbage in eastern Tokyo was found with a high level of radioactive cesium in the fly ashes caught in the incinerator filter. Edogawaku is loed at the eastern end of Tokyo. Along with its northern neighbor Katsushikaku, Edogawaku seems to have been in denial of the elevated ...Get Price
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 . Since this is considered safe for drinking water, and combined with monitoringGet Price
Approximating Personal Exposure to Radioactive Cesium In ...
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.Get Price

In Mark of Progress, SRS Crews Remove Cesium Columns from Tank Closure Unit. February 9, 2021. Aiken, For the first time, Savannah River Remediation (SRR), the liquid waste contractor at the Savannah River Site (SRS), has removed columns that are filled with cesium in a demonstration project designed to accelerate removal of radioactive salt waste from underground tanks.Get Price
UW Research Training Building Remediation | EHS
The facility was closed for cleanup on May 2, 2019 after a small amount of a radioactive material called cesium137 was released on the building's loading dock by a Department of Energy (DOE) subcontractor that was removing a piece of equipment called an irradiator. Read the investigation report for more information about the incident.Get Price
Innovative Highly Selective Removal of Cesium and ...
· Highly selective removal of Cesium and Strontium is critical for waste treatment and environmental remediation. Cesium137 is a betagamma emitter and Strontium90 is a beta emitter with respective halflives of 30 and 29 years. Both elements are present at many nuclear sites.Get Price
How Much Radioactive Cesium Was Discharged from Rivers to ...
· Radioactive cesium discharge through rivers into the ocean was considered to be the third release route, which comes after the direct release route from TEPCO HD Fukushima Daiichi Nuclear Power Station (1F) into the ocean and the atmospheric radioactive fallout route.Get Price

(PDF) CORRELATION BETWEEN RADIOACTIVE CESIUM AND THE ...
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.Get Price
