the activity concentrations of 226ra, 232th, 40k and 137cs in water and sediment samples from hot springs of mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (hpge) detectors with relative efficiencies 38.5% and 55%. the activity concentrations of 226ra, 232th, 40k and 137cs in sediment samples from hot spring donbe...

The accumulation and distribution of 40K and 137Cs in tropical plant species were studied through measurements of gamma-ray spectra from mango, avocado, guava, pomegranate, chili pepper, papaya and manioc trees. Our goal was to infer their differences in the uptake and translocation of ions to the aboveground plant parts and to establish the suitability of using radiocaesium as a tracer for the...

In this study, the long-term (i.e., over a 27-year period) dynamics of 137Cs content are presented for seven species fish in both cooling pond (CP) Chornobyl Nuclear Power Plant and Kaniv Reservoir (KR). The decline specific activity exhibits various patterns. For certain years KR, belonging to different ecological groups experienced an increase rather than decrease levels 137Cs. From 2012 2014...

Two spectrometers were examined for the discrimination of low-energy part 137Cs gamma-ray spectrum. Obtained spectra from compared with each other. To perform an exact comparison, partial and complete processes realized.
