Detection of radioactive contamination, using Geiger-Muller counters

Temperature Effect and Its Elimination in Geiger - Muller Tube Counters

It has been found that in the usual form of the Geiger-Miiller tube counter the rate of counting is affected by changes of temperature. The rate of counting, at a fixed potential applied to the tube, decreases as the temperature is increased. This indicates an increase in the density of the gas in the counter. Since it is hermetically sealed this can only be caused by evaporation of volatile ma...

Radioactive Contamination Detection in Water Using Wireless Sensor Network

Radioactive contamination is the result of regular operation of nuclear power plants, leakage or accident during the production, or use of radionuclides (radioisotopes). They occur throughout the nuclear fuel cycle and continue to give off harmful radioactive particles and rays for very protracted periods. Radioactive elements can contaminate water adversely affecting human health as well as aq...

Radioactive contamination of scintillators

Low counting experiments (search for double β decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background α, β, γ spectrometry) require extremely low background of a detector. Scintillators are widely used to search for rare events both as conventional scintillation detectors and as cryogenic s...

Assessment of radioactive contamination in water bodies around mine workings using radiation counter

The vulnerability of water bodies to contamination within the neighbourhood of open mine cast environ cannot be overemphasized. Evidence of radioactive trace elements associated with the target minerals in the Plateau State (Nigeria) showed the extent of this vulnerability. In order to address this challenge, the radioactivity levels of water samples from mine ponds, streams, wells, and borehol...
