There has been recent and growing interest in applying Cerenkov radiation (CR) for biological applications. Knowledge of the production efficiency and other characteristics of the CR produced by various radionuclides would help in accessing the feasibility of proposed applications and guide the choice of radionuclides. To generate this information we developed models of CR production efficiency...

conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...

Marine sediment samples were collected along the Jeddah coast, Red Sea, Saudi Arabia, in order to assess radiation hazards and exposure human marine living organisms. Using collaborative techniques, grain size, mineralogical characteristics, natural radioactivity investigated. To examine influence of characteristics over distribution measured radionuclides, resulting data statistically processe...

background: investigation on the natural radionuclides 238u, 232th, 40k and natural fallout radionuclide 210po in the prominent plants species of western ghats tropical forest near kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. materials and methods: the prominent plants species of the region evodia roxburghiana and eleaocarpus oblan...

On 11 March 2011, the Fukushima nuclear disaster shocked the world. A 9.0 magnitude earthquake induced a tsunami, which then shut down the power supply of cooling system of the nuclear plant. The nuclear reactor exploded due to overheat and hydrogen accumulation. Radioactive materials were released and plutonium was detected positive in the soil of the power plant. It is the most severe nuclear...

n 1987 the International Agency for Research of Cancer (IARC) evaluated radon and its decay products as human carcinogens (1). Large epidemiologic studies conducted in Western Europe in the Õ90s showed that this radioactive gas accounted for 50 to 90% of a radiological dose (2). Very high residential concentrations of radon were measured in Sweden and Finland (3-5). They were 5,000 times higher...

To evaluate the environmental contamination and contributory external exposure after the accident at the Fukushima Nuclear Power Plant (FNPP), the concentrations of artificial radionuclides in soil samples from each area were analysed by gamma spectrometry. Six artificial radionuclides ((131)I, (134)Cs, (137)Cs, (129m)Te, (95)Nb and (136)Cs) were detected in soil samples around FNPP. Calculated...

Radiation exposure with use of intraoperative fluoroscopy is a potential orthopedic occupational risk factor. The purpose of this study was to perform a prospective comparison of hand versus eye radiation exposure associated with mini-C-arm utilization and to test the hypothesis that routine mini-C-arm does not yield hand or eye dosages exceeding current recommended levels. Over a 12-month peri...

The development of radionuclide therapies during the past few decades provides a growing body of data on radiobiologic effects, including normal tissue toxicities and antitumor efficacy. Information on normal tissue toxicity from radionuclides is more limited than that from external beam radiation and appears to be more variable. Much of the increased variability is attributed to heterogeneous ...

Radioisotopes, also known as radionuclides, are atoms with unstable nuclei that emit ionizing radiation [...]
