Radon concentration measurement in water reservoirs for some areas of north Baghdad by RAD7 [PDF]
Journal of Physics: Conference Series, 2021 Abstract Radon is a naturally occurring, odorless, colorless, radioactive, tasteless, and noble gas. Radon concentrations have been measured by the usage of alpha spectroscopy (RAD-7). The RAD-7 measuring process is based on detecting alpha particles produced from the disintegration of radon and its products using a solid-state alpha ...

The method for recalibration of thoron concentration reading of RAD7 and obtaining the thoron exhalation rate from soil surface [PDF]
Nuclear Technology and Radiation Protection, 2013 Thoron exhalation rate can be obtained through the combination of the “accumulation chamber” technique and RAD7. Thoron’s rapid decay causes the intake path and the air flow rate to become important factors in calibration.

RAD7 Gene of Saccharomyces cerevisiae: Transcripts, Nucleotide Sequence Analysis, and Functional Relationship between the RAD7 and RAD23 Gene Products [PDF]
Molecular and Cellular Biology, 1986 The RAD7 gene of Saccharomyces cerevisiae was cloned on a 4.0-kilobase (kb) DNA fragment and shown to provide full complementation of a rad7-delta mutant strain. The nucleotide sequence of a 2.2-kb DNA fragment which contains the complete RAD7 gene was determined. Transcription of the RAD7 gene initiates at multiple sites in a region spanning positions

Repair of plasmid and genomic DNA in arad7Δ mutant of yeast [PDF]
Nucleic Acids Research, 1995 Repair of UV-induced cyclobutane pyrimidine dimers (CPDs) was examined in a yeast plasmid of known chromatin structure and in genomic DNA in a radiation-sensitive deletion mutant of yeast, rad7 delta, and its isogenic wild-type strain. A whole plasmid repair assay revealed that only approximately 50% of the CPDs in plasmid DNA are repaired after 6 h in

The yeast DNA repair proteins RAD1 and RAD7 share similar putative functional domains [PDF]
FEBS Letters, 1991 Sequence information on eukaryotic DNA repair proteins provided so far only few clues concerning possible functional domains. Since the DNA repair process involves a strict sequential complex formation of several proteins [(1988) FASEB J. 2, 2696–2701], we searched for special protein‐protein interacting domains, which consist of tandemly repeated ...
