Environmental Xe-133 radiation monitoring method by thermoluminescence dosimeters after accidental release from nuclear power plant.

Detection of (133)Xe from the Fukushima nuclear power plant in the upper troposphere above Germany.

After the accident in the Japanese Fukushima Dai-ichi nuclear power plant in March 2011 large amounts of radioactivity were released and distributed in the atmosphere. Among them were also radioactive noble gas isotopes which can be used as tracers to test global atmospheric circulation models. This work presents unique measurements of the radionuclide (133)Xe from Fukushima in the upper tropos...

Environmental Background Radiation Monitoring Utilizing Passive Solid Sate Dosimeters

Environmental contamination and external radiation dose rates from radionuclides released from the Fukushima Nuclear Power Plant.

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...

Uncertainty analysis of absorbed dose calculations from thermoluminescence dosimeters.

Thermoluminescence dosimeters (TLD) are widely used to verify absorbed doses delivered from radiation therapy beams. Specifically, they are used by the Radiological Physics Center for mailed dosimetry for verification of therapy machine output. The effects of the random experimental uncertainties of various factors on dose calculations from TLD signals are examined, including: fading, dose resp...
