Background: The concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of Rooppur Nuclear Power Plant (RNPP) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. Materials and Methods: Soil samples were collected from 40 locations in and around the proposed site of Rooppur Power Plant and determined ...

This isotope of curium is radioactive and decays by the emission of an a-particle to form Pu2% which, in turn, is also radioactive. Cm242 has a half life of 150 days and its radioactive daughter, PUCK, has a half life of 50 years. This isotope of plutonium decays by the emission of an a-particle to form U234 which has a half life of 233,000 years. Shortly after the organization of the Atomic En...

Nuclear weapons making and testing, operation of enterprises of the nuclear industry, of military and civilian nuclear fleet, as well as peaceful nuclear explosions – all that led in the USSR to release of radioactive products into the environment. In some parts of the FSU radioactive contamination exceeded permissible levels. The necessity of remediation of such territories became evident. The...

1. The rate of radioactive vitamin B12 excretion into plasma and bile from the isolated perfused rat liver and into bile in vivo has been measured after the intramuscular injection of radioactive cyanocobalamin at various time-intervals before study. 2. With an interval of labelling of 10 or more days, the release of radioactive vitamin B12 over 4 h by the isolated perfused liver was linear and...

BACKGROUND National surveillance for chemical incidents is being developed in the UK. It is important to improve the quality of information collected, standardise techniques, and train personnel. OBJECTIVE To define the extent to which eight National Poison Information Service specialists in poison information agree on the classification of calls received as "chemical incidents" based on the ...

INTRODUCTION This paper examines a number of US chemical industry incidents and their effect on equity prices of the incident company. Furthermore, this paper then examines the contagion effect of this incident on direct competitors. METHOD Event study methodology is used to assess the impact of chemical incidents on both incident and competitor companies. RESULTS This paper finds that the ...

Radioactive wastes are generated during nuclear fuel cycle operation, production and application of radioisotope in medicine, industry, research, and agriculture, and as a byproduct of natural resource exploitation, which includes mining and processing of ores, combustion of fossil fuels, or production of natural gas and oil. To ensure the protection of human health and the environment from the...
