Alpha-particle spectrometry is the most frequently used technique for the activity determination of alpha emitters, such as radium, uranium, plutonium, americium and thorium in environmental samples. In this paper an extensive uncertainty budget is presented for a typical alpha-particle spectrometry measurement of the Ra activity concentration in drinking water. The most influential parameters ...

Background: Hair dyes are the important materials widely used by various peoples in Iraq and other countries. The present work investigates the presence of the effective radium content and radon exhalation rate in hair dyes samples. Materials and Methods: Twenty  hair dyes  samples were collected from Iraqi markets. Sealed can technique using LR-115 type II plastic track detector s ha...

Patients recently treated with radioactive isotopes may present problems or even hazards during physical examination, operation or autopsy, especially following the use of iodine isotopes and 198Au. 32P is rarely a significant hazard. Contamination of victims of radiation accidents may be a problem initially, but they are usually promptly decontaminated. Guidance of the hospital's radiation saf...

Distribution of salinity, dissolved oxygen, nitrate, phosphate, and silicate are presented for the western Gulf of Mexico in 1978. Plots of chemical concentration versus potential density are used to identify the presence of gulf water, tropical Atlantic central water, Antarctic intermediate water, Caribbean midwater, and upper North Atlantic deep water within the upper 1600 m of the western Gu...

Introduction: This study covered the assessment of the natural radioactivity levels and heavy metalsconcentration in dust samples collected from selected schools in the holy Governorate of Karbala. The purpose of thisstudy was to assess the radiological health and safety impact of dust pollution on the children going to school. Material and Methods:</...

This paper aims to estimate a potential radiological risk from different kinds of coals used for domestic heating in Serbia, by measuring the activity concentration radionuclides and radon exhalation rate. The obtained mass rate ranges (5.3 ? 3.1) mBqkg?1s?1 (70.3 9.4) mBqkg ?1s?1 was highest lignite type coal. It is estimated that coal stored basement could contribute up 50 Bqm?3 indoor at gro...
