Environmental transfer factors: methodologies for transfer factor-based environmental monitoring2008
AbstractAbstract
[en] The present chapter provides brief details on experimental setups, needed to evaluate the transfer, in various environmental matrices. These experiments would also help to study the attainment of equilibrium conditions, which is of prime importance to evaluate the transfer factors. These experiments are only guidelines for achieving the objective, however, they are required to the modified as per the needs and convenience of the users

AbstractAbstract
[en] Tritium is the heaviest and only radioactive isotope of hydrogen. Apart from its natural origin, it is also produced as an activation product in PHWR type reactors which utilizes heavy water as moderator and coolant as well. Radioactive isotopes are useful in tracing the movement of water in the environment. The measurements of tritium for a large number of applications have been demonstrated in groundwater hydrology. This paper attempts to demonstrate the uses of tritium monitoring in assessing the water homogeneity in Rana Pratap Sagar Lake waters. (author)

AbstractAbstract
[en] This paper discusses, both the techniques that are presently used in India and those that have the potential for use in the field of Bioassay monitoring. These techniques can also be employed for the measurements of actinides in air, and other biological and environmental samples. Neutron Activation Analysis (NAA) appears to be the most sensitive technique for determination of 232Th and 238U in bioassay samples at levels well below the DRL. FTA appears to be the only adequately sensitive technique (about 1000 times more sensitive than alpha spectrometry) presently available to detect Pu in bioassay sample at levels below DRL. HR-ICP-MS can also be used to measure plutonium in bioassay samples below DRL but the prohibitive cost and the complexity of analysis renders the technique impracticable for routine analysis. These techniques, therefore, require to be developed, standardized and exploited for internal dosimetry purposes

AbstractAbstract
[en] A comprehensive environmental surveillance programme is being pursued by Health Physics Division of BARC at Tarapur nuclear site for the last fifteen years or so. At present the main concern of this programme is to monitor the environmental impact of the 400 MWe Atomic Power Station operating at the site since 1969. A 5-year pre-operational survey established the base line radioactivity levels and their variation as well as the critical pathway of population exposure. The monitoring programme involves employment of a wide range of techniques such as thermoluminescence dosimetry, whole body counting, radioactivity analyses of food samples and marine sediments and organisms. The results have all along indicated that the environmental contaminations due to power station operation is insignificant. (author)

Environmental transfer factors: methodologies for transfer factor-based environmental monitoring2008
AbstractAbstract
[en] Man is always exposed to pollutants either natural or anthropogenic. Environmental monitoring is one of the most important methods to assess exposure levels and their effects on human beings, ecology and environment. After completion of all exercises of environmental monitoring the ultimate aim is to communicate the results, either to the regulatory authorities or to the general public. This remains unaddressed until data interpretation, it's statistical analysis and communicable inferences are not drawn. To perform statistical analysis of environmental data and it's interpretation, a general approach is described in this paper

AbstractAbstract
[en] This paper presents the results of a control study conducted in an aquarium containing the radioactive effluent, where fishes were reared to obtain data on uptake of 3H, 134Cs, 137Cs and 60Co by fishes. The concentrations of studied radionuclides were ascertained by replicate analysis of effluent water in the experimental aquarium. The fishes were periodically sampled from the aquarium and analysed by high resolution gamma spectrometry to evaluate 134Cs, 137Cs and 60Co. Tissue free tritium (TFT) and organically bound tritium (OBT) contents were estimated using packard 3170 liquid scintillation counter. The study was continued for a period of seven months to assess the equilibrium between effluent water and fishes. At equilibrium conditions the water to fish transfer factors for OBT, 137Cs, 134Cs and 60Co were found to be 0.02, 177, 143 and 18 respectively. (author)

AbstractAbstract
[en] A simple one step method is described for the simultaneous determination of all the alpha-emitting transuranic nuclides in the primary circuit of the nuclear power plant. The method exploits the intrinsic chemical characteristics of the system and obviates the use of external chemicals. At the pH of the system (8-10) hydroxides of the actinides are coprecipitated with Fe(III) present as corrosion product. This precipitate is collected on a 25 mm membrane filter with 0.1 m pore in a form suitable for alpha spectrometry without need for electrodeposition. The alpha spectrum is comparable to that obtained with electrodeposition. The method gives consistently higher yield (>90%) and does not need use of tracers for the quantitative determinations.
