Survey Heavy Metal Content in Cydonia Fruits Collected from Market Sites in Hamadan, Iran

Background & Aims of the Study: High concentration of toxic metals in foodstuffs is among the public interest and therefore requires rapid methods to survey the concentration of these contaminants. In the present study, concentration of some heavy metals (lead, copper and arsenic) in Cydonia fruits from Hamadan city market were determined by atomic absorption spectrophotometry. ...

A comparison of the dose from natural radionuclides and artificial radionuclides after the Fukushima nuclear accident

Due to the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, the evacuees from Namie Town still cannot reside in the town, and some continue to live in temporary housing units. In this study, the radon activity concentrations were measured at temporary housing facilities, apartments and detached houses in Fukushima Prefecture in order to estimate the annual internal exposure dose of resid...

natural radioactivity of granites used as building materials in iran

the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...

Radiological risk analysis of sediment from Kutubdia island, Bangladesh due to natural and anthropogenic radionuclides

To assess the environmental radioactivity levels and hence to determine the population exposure in Kutubdia Island, Bangladesh the sediment samples were analyzed by using gamma ray spectrometry. In those sediment samples the average activity concentration of natural radionuclides 238U, 232Th and 40K were found 15.39±1.67, 38.35±0.76 and 475.51±21.15 Bq/kg respectively. ...
