This study presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation around radiological sections in Federal Teaching Hospital Gombe, Gombe State, Nigeria using a well calibrated Rados-200 meters Global Positioning System (Garmin 765). The mean annual outdoor equivalent dose 0.078 mSv/y. was measured. Mean effective doses 0...

In April 2020, several wildfires took place in and around the Chernobyl exclusion zone. These fires reintroduced radioactive particles deposited during 1986 disaster into atmosphere, causing concern about a possible radiation hazard. Several countries stations of International Monitoring System measured increased Cs137 levels. This study presents analyses made by RIVM SCK CEN/RMI 2020 wildfires...

A modern human receives most of the radioactive annual dose in buildings from radon and its progeny, which can cause lung cancer. In such conditions, design radon-safe is an urgent task context preserving population collective health. The paper shows inefficiency using flux density soil surface as a criterion for potential hazard construction site due to significant temporal spatial variability...

Within the next few decades, several hundred thousand tons of metal are expected to be removed from nuclear facilities across the U.S. Department of Energy (DOE) complex as a result of decontamination and decommissioning (D&D) activities. These materials, together with large quantities of tools, equipment, and other items that are commonly recovered from site cleanup or D&D activities, constitu...

This paper aims to estimate the rate of particulate contaminants emitted by multiple sources, whose values are unknown, using identified receptors distributed around sources. In a nuclear emergency with release radionuclides into atmosphere, in order make correct decision, it is necessary identify source term and its rate, as well meteorological data, essential factors for defining direction si...

Sir, the big flooding in Thailand in 2011 is one of the problematic flooding in Asia. It causes several destroying to many things in the disaster areas. An important concern is on the effect on the setting with the radioactive elements usage. In Thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. Luckily, ...

Radon gas and its radioactive daughters have been extensively studied on Mt. Etna, both in local volcanic rocks all types of fluid emissions from the volcano (crater gases, fumaroles, mofettes, soil groundwaters). The first measurements date back to 1976 were carried out crater plume. Since then, fifty-four scientific articles published. largest majority them (more than 50%) correlated radon wi...
