Molecular gas phase counterparts to solid state grain mantles features: implication for gas/grain chemistry
We present ISO SWS (AOT6) observations of the protostellar object RAFGL 7009S. This source is particularly interesting for the characterisation of chemistry arising from grain surfaces andmantles, since the solid state features ofmany simple molecules such asH2O,CO,CO2, CO2 andCH4 are detected, together with weaker features not yet unambiguously identified. Gas phase H2O, CO2, CH4 and CO can al...
متن کاملEnvironmental radioactivity in the UK: the airborne geophysical view of dose rate estimates.
This study considers UK airborne gamma-ray data obtained through a series of high spatial resolution, low altitude surveys over the past decade. The ground concentrations of the naturally occurring radionuclides Potassium, Thorium and Uranium are converted to air absorbed dose rates and these are used to assess terrestrial exposure levels from both natural and technologically enhanced sources. ...
متن کاملOccupational exposure of phosphate mine workers: airborne radioactivity measurements and dose assessment.
Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...
متن کاملTRANSIENT DECREASED SERUM TESTOSTERONE AFTER EXPOSURE TO MUSTARD GAS
The effects of exposure to chemical weapons containing sulfur mustards on the serum levels of total and free testosterone. gonadotropins and prolactin was investigated in young Iranian men. In the first five weeks after injury both serum total and free testosterone were significantly decreased as compared to control values. Three of 13 men had total testosterone below 300 ng/dL and two of ...
متن کاملAssessment of Effective Dose Equivalent from Internal Exposure to 222Rn in Ramsar City
Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...
