lung tumors of different histologies and apparent sites of origin. Hematite-210Po produces combined epidermoid and adenocarcinomas in the peripheral lung, while BP-hematite produces mainly epidermoid carcinomas of the major bronchi and trachea. To determine whether cells in the lung are differentially sensitive to the two types of carcinogen or whether the carcinogens are reaching and acting at...

The Middle East is a hot spot of dust, and there are reports as much 1400 µg m−3 dust in aerosols from Kuwait, which among some the highest loadings globally. A significant volume literature has emerged on dust–air-quality–human-health, World Health Organization its recent air quality guidelines lowered limit annual PM2.5 exposure to 5 μg previous 10 m−3. We present mini-review based screening ...

Implanted long-lived radon decay products in glass surfaces have been used as a measure of past radon exposure in homes. Special track-etch devices (so-called 'retro-detectors') attached to the glass surface, have the ability to specifically measure the implanted activity of 210Po in situ. Calibrating these devices for 210Po is fairly straightforward, but the retro-detectors are also sensitive ...

This paper presents an investigation of the retention of environmental radon daughters, 210Po (alpha particle emitting radio-nuclide) and 210Bi (beta particle emitting radio-nuclide), in lipid and protein fractions of the cortical grey and subcortical white matter from the frontal and temporal brain lobes of patients who had suffered from Alzheimer's disease or Parkinson's disease, of cigarette...

The pollution level of Lake Bafa was investigated by collecting fish samples {Dicentrarchus labrax (sea bass), Liza ramada (mullet) and Anguilla anguilla (eel)}, surface sediment, and core samples. In all these samples, 210Po and 210Pb concentrations were estimated, and total annual dose rates were obtained for each species. Some heavy metal (Cr, Ni, Pb, Cd, Mn, Fe, and Zn) concentration levels...

Significant efforts have been made by the International Commission on Radiological Protection (ICRP) to establish a reliable basis of equivalent and effective doses due radionuclides. The ICRP over years has updating dose coefficients include recent developments make it more realistic. This perspective highlights some issues that warrant methodology used for estimating 210Po humans. need underp...
