Protection Against Radioactive Contamination of Sea

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...

Thule-2003 - Investigation of Radioactive Contamination

Radioactive contamination of ZnWO4 crystal scintillators

The radioactive contamination of ZnWO4 crystal scintillators has been measured deep underground at the Gran Sasso National Laboratory (LNGS) of the INFN in Italy with a total exposure 3197 kg × h. Monte Carlo simulation, time-amplitude and pulse-shape analyses of the data have been applied to estimate the radioactive contamination of the ZnWO4 samples. One of the ZnWO4 crystals has also been te...

Measurement of Fukushima-related radioactive contamination in aquatic species.

The Great East Japan (Tohoku) Earthquake and consequent tsunami of March 11, 2011, caused immense damage and loss of life in Japan. It is estimated that over 15,000 people died and in excess of 2,500 persons are still unaccounted for (1, 2). The tsunami that struck the Fukushima Dai-ichi Nuclear Power Plant (NPP) led to breakdown of the reactor cooling systems, resulting in overheating of fuel ...
