for the first time, on the basis of spitak earthquake experience (armenia, december 1988), it was found that an earthquake causes intensive and prolonged radon releases that are quickly dispersed in the open air and that is why they are not usually registered but contrastingly displayed in covered premises (such as dwelling houses, schools, kindergartens) even if they are at a considerable dist...

Attorneys and jurors will have their own ideas of radon health risks before hearing any testimony. For most people, without radiation training, radon is mysterious because they cannot detect the presence of radon with their five senses. For some, radon may not represent a significant danger because people do not see any direct evidence of lung cancer due to radon. For others, radon as a radioac...

It is now generally recognized in most countries that Radon-222 is the principal source of potentially hazard1,2 ous radiation source in the general population. Simple devices used to measure Radon levels in the air record the number of alpha particle tracks, evidence of the radioactive disintegration of Radon. The unit of radioactivity of nuclides (isotopes of elements that disintegrate sponta...

Radon is the most harmful natural contaminant in indoor atmosphere of buildings. The noble gas, after cigarette smoke, biggest cause lung cancer, and today study its diffusion, distribution, concentration around world has attracted many researchers field radiation protection environmental health. Typically, output data obtained from traditional methods measuring radon buildings limited to infor...

Abstract This study focuses on the evolution of radon concentrations in tap water samples primary schools Najaf city using a RAD-7 detector. Annual effective doses children were calculated. A Geographic Information System technique was used for mapping concentrations, annual dose (AED) ingestion, and inhalation. It found that average value AED due to ingestion 0.236 ± 0.020 μSv/year, while 0.01...

In this study, measurement of alpha emitters such as radon-222, radium-226, and uranium-238 levels in Iraqi medical plants samples using CR-39 detector. As well as, annual average internal dose (AAIED) risk an excess cancer fatality per million persons (RECFPMP) due to ingestion radon, radium, uranium from the present study were calculated. The values with stander error activity unit Bq/kg 5.22...
