The annual effective dose from natural sources of ionising radiation in Canada
Radiation Protection Dosimetry, 2004A review and analysis of published information combined with the results of recent gamma ray surveys were used to determine the annual effective dose to Canadians from natural sources of radiation. The dose due to external radiation was determined from ground gamma ray surveys carried out in the cities of Toronto, Ottawa, Montreal and Winnipeg and was ...

Effectance, committed effective dose equivalent and annual limits on intake: what are the changes?
Journal of Radiological Protection, 1990The International Commission on Radiological Protection has recently published draft recommendations which include proposals for new weighting factors, WT for use in calculating effective dose equivalent, now called 'effectance'. The author outlines the concept of effectance, compares committed effectance with the old committed effective dose ...

Radiation Protection Dosimetry, 2004
A total of 26 different food types and 12 elaborated diets were analysed by low-level gamma spectrometry to measure their content of 238U(234Th), 228Ra(228Ac), 226Ra(214Pb), 210Pb, 137Cs and 40K. The concentrations of these radionuclides measured in some imported foodstuffs were compared with those measured in some locally produced ones.

An estimation of the annual effective dose to the Canadian population from medical CT examinations
Journal of Radiological Protection, 2010This study was carried out to assess the annual per capita effective dose from medical diagnostic procedures using computed tomography (CT) in Canada. Relevant data concerning the nature and the frequency of various diagnostic CT examinations were obtained from the reports on Medical Imaging in Canada and Diagnostic Services in Ontario.

Annual solar UV exposure and biological effective dose rates on the Martian surface
Advances in Space Research, 2004The ultraviolet (UV) environment of Mars has been investigated to gain an understanding of the variation of exposure throughout a Martian year, and link this flux to biological effects and possible survival of organisms at the Martian surface. To gain an idea of how the solar UV radiation varies between different regions, including planned landing ...

Assessment of annual effective dose due to natural gamma radiation in Zanjan (Iran)
Radiation Protection Dosimetry, 2008The outdoor and indoor measurement of natural gamma radiation in Zanjan province (Iran) was made using a Geiger-Muller dosemeter. The average outdoor and indoor dose rates were determined as 127 +/- 20 and 135 +/- 23 nSv h(-1), respectively. The average annual effective dose was calculated as 0.82 mSv, which is more than the same value worldwide.

Journal of Exposure Science & Environmental Epidemiology, 2015
The Chernobyl Nuclear Power Plant (CNPP) accident represents one of the most significant civilian releases of 137Cesium (137Cs, radiocesium) in human history. In the Chernobyl-affected region, radiocesium is considered to be the greatest on-going environmental hazard to human health by radiobiologists and public health scientists.

Potassium concentrations and annual effective dose of the customary food stuffs in Mexico
Journal of Radioanalytical and Nuclear Chemistry, 2013Measurement of radionuclides concentration in foodstuffs allows to assess the intake’s assimilated dose. This contributes at least one-eighth of the mean annual effective dose due to natural sources. Among the trace elements in foodstuff, potassium is one of the most important elements.

Annual Effective Dose of High Level Natural Radiation Areas of Ramsar
2013The exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. For most individuals, this exposure exceeds that from all man-made sources combined. In this study the annual effective dose in high level natural background radiation (HLNBR) areas of northern city of Ramsar in Iran was ...
