Experimental technique to measure thoron generation rate of building material samples using RAD7 detector [PDF]
Radiation Measurements, 2013 Thoron ( 220 Rn) is the second most abundant radon isotope in our living environment. In some dwellings it is present in significant amount which calls for its identification and remediation. Indoor thoron originates mainly from building materials. In this work we have developed and tested an experimental technique to measure thoron generation rate in ...

DNA Repair, 2004
Nucleotide excision repair (NER) in eukaryotes removes DNA base damage as an oligonucleotide in a complex series of reactions. The nature of the dual incision reactions on either side of the damaged base has been extensively investigated. However, the precise mechanism of cleavage of the phosphodiester backbone of the DNA by the NER endonucleases and ...

Determination of radon concentration in water using RAD7 with RAD H2O accessories
AIP Conference Proceedings, 2015In the last decade, the radon issue has become one of the major problems of radiation protection. Radon exposure occurs when using water for showering, washing dishes, cooking and drinking water. RAD7 and Rad H20 accessories were used in order to measure radon concentration in water sample.

Excision of pyrimidine dimers and interstrand DNA crosslinks was examined in the deletion mutants rad7-delta 1, rad23-delta 1, and rad7-delta 1 rad23-delta 1. These mutants remove pyrimidine dimers and crosslinks much less efficiently than the RAD+ strains; only 30-60% of pyrimidine dimers and 25-40% of crosslinks are removed even after prolonged ...

Radon gas is a significant health threat linked to thousands of preventable deaths each year. In this paper, radon activity concentration is measured in 260 groundwater samples collected from 65 villages in the Bathinda district of Punjab State, India, using Rad7, an electronic radon detector (Durridge Co., USA). The radon concentration varies from 0.9

Applied Radiation and Isotopes, 2015
A procedure for the determination of (222)Rn in environmental water samples using liquid scintillation counting (LSC) was applied and optimized. A minimum detectable activity of 0.029Bql(-1) in a 20ml glass vial (10ml water sample mixed with 10ml of liquid scintillation cocktail) has been achieved during 300min of measurement time.

The ability to remove ultraviolet (UV)-induced pyrimidine dimers from the nuclear DNA of yeast was examined in two radiation-sensitive (rad) mutants and one methyl methanesulfonate-sensitive (mms) mutant of the yeast Saccharomyces cerevisiae. The susceptibility of DNA from irradiated cells to nicking by an endonuclease activity prepared from crude ...
