Abstract. Due to several radioactive accidents at the Mayak Production Association, a facility for production of weapon plutonium put on line in 1948 in the Southern Urals (Russia), an substantial part of the Southern Urals territory was contaminated by long-lived radionuclides. One of the such accident was the wind resuspension of radionuclides (2⋅10Bq) from the shoreline of Karachai lake used...

Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...

PURPOSE A fiducial tracking system based on a novel radioactive tracking technology is being developed for real-time target tracking in radiation therapy. In this study, the authors calculate the radiation dose to the patient, the spouse/caretaker, and the medical staff that would result from a 100 microCi Ir192 radioactive fiducial marker permanently implanted in the prostate of a radiation th...

To the Editor: On March 11, 2011, Japan was struck by a magnitude 9.0 Mw earthquake. The results were severe, as more than 15,000 people were killed by the earthquake and the following tsunami.1 The aftermath of the disaster was a level 7 nuclear meltdown in Fukushima, matching only the Chernobyl disaster.1,2 However, a recent report of the World Health Organization showed that, to date, no dea...

Acute radiation-induced symptoms reported in survivors after the atomic bombings in Hiroshima and Nagasaki have been suspected to be associated with rain that fell after the explosions, but this association has not been evaluated in an epidemiological study that considers the effects of the direct dose from the atomic bombs and other factors. The aim of this study was to evaluate this associati...

Abstract The protection and preservation of human health under present-day conditions high urbanization rate is one the priority tasks contemporary construction. And here, environmental safety residential buildings to be constructed most important factors. It significantly affected by ionizing radiation for which radioactive radon gas sources. level public exposure depends on concentration in a...

Radioactive materials which occur naturally and expose people to radiation widely, are known by the acronym 'NORM'. Exposure NORM is often increased human activities, eg burning coal, making using fertilisers, oil gas production.
 Many natural contain radioactive elements (radionuclides). The earth's crust constantly leaks radon into our atmosphere. However, while level of individual expos...

The need for a system of radiological protection of the environment drives regulators to urge scientists on conceptualisation of methods to demonstrate that the environment is protected against radioactive contaminants. One of the major difficulties in the implementation of ecological risk assessment for radioactive pollutants is the lack of data for wildlife chronic internal exposure to alpha ...

Across the globe, radioactive consumer products are widely marketed for daily use. The present study investigated commercially available ion paint, and evaluations were using gamma (?)-ray spectroscopy Geant4 Monte Carlo (GMC) simulations. An assessment of a radiological risk arising from such in painting living areas is conducted when Technologically Enhanced Naturally Occurring Radioactive Ma...

Chernobyl, the largest ever nuclear accident, caused a huge release of radioactive isotopes, including nearly 2x10(18) Bq of iodine-131. Four years later an increase in thyroid cancer incidence, virtually all papillary carcinomas in children, occurred in the highly exposed areas. The increase has continued, and with increasing latency the tumour molecular and morphological pathology has changed...
