The radiation monitoring at `The Marsh`

Abstract

Since 1979 the Kozloduy NPP has been dumping radioactive waste waters into a canal system situated on a lowland close to the Danube river and known as `The Marsh`. Contaminated soil strips had been located along the canals. The sites have been marked and the exposure rates on-surface and in-depth have been measured. Soil samples have been investigated by gamma-ray spectrometry and selected samples evaluated for Pt and Sr-90 content and alpha and beta radioactivity. Data on exposure rates from 4430 points have been processed. On the canal bottom the exposure rates vary from 30 to 100 {mu}R/h and on the canal sides they exceed 100 {mu}R/h. The main sources of activity have been identified as Cs-137 and Co-60. Results from agro-ecological characterization of the soils have been presented. The following possible ways of soil treatment and decontamination are discussed: burying the polluted earth; chemical tilling and treating with zeolites; deriving the artificial radionuclides by an appropriate crop-rotation; creating an experimental field-range; creating an wood massive; no special treatment. 16 refs., 2 tabs.
