[ 1 ] - Natural radioactivity concentration in raw materials used for manufacturing refractory products

Background: Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of th...

[ 2 ] - Derived intervention levels for mostly consumed foodstuffs in Iran

ABSTRACT Background: Measures to protect the public following an accidental release of radionuclides to the environment will depend on the circumstances including the extent of the potential hazards. The projected levels of risk are an important precondition in emergency planning. The levels can be expressed in terms of concentration levels in the environment o...

[ 3 ] - Transfer of 226Ra and 137Cs from tea leaves to drinking tea

Background: Two of the important radionuclides which are entered to environment and human diet are radium-226 (226Ra) and cesium-137 (137Cs). It is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. An experiment has been performed at the environmental monitoring section...

[ 4 ] - Determination of 226Ra and 228Ra concentrations in foodstuffs consumed by inhabitants of Tehran city of Iran

ABSTRACTBackground : The presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. Measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations. Materials and methods: A total of 56 samples from 18 different foodstuf...
