premature chromosome condensation (pcc) appears to have a possible utility for biological dosimetry purposes. the pcc technique may be adapted for cases of suspicion of overexposure where sampling is performed at least one day after an accident. for this purpose, human blood samples were exposed in vitro to 60co up to 10 gy and the pcc technique was performed immediately after irradiation. anal...

Prentul Kediri cayenne pepper is a local variety that has the potential to be developed into new superior through breeding of gamma-ray mutations. The purpose study find out diversity and degree similarity in plants M1 generation based on qualitative character. research was conducted August 2021-February 2022 at field, Ketindan Village, Malang City. This completely randomized block design with ...

Background: Previous investigations have revealed, cimetidine, a histamine H2-receptor antagonist, show radioprotective effects against gamma- and neutron-induced micronuclei in bone marrow erythrocytes. In this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine H2-receptor antagonists, was investigated. Materials and Methods : Balb/c m...

Variation in genetic constituent leads to increasing phenotypic expression of the quantitative characters of individuals. This variation is induced by mutation and the variability was evaluated on the quantitative traits such as, days to germination, percent germination, root length, brix percent and yield of sugarbeet mutant at M1 generation by the effect of radiation. The results were showed ...

A whole cell extract prepared from Schizosaccharomyces pombe was shown to be active in an assay for repair of plasmid DNA damaged by either ultraviolet (UV) light or gamma-radiation. The assay allows for analysis of repair synthesis at single-strand nicks generated by gamma-rays and analysis of the incision step and repair synthesis in UV-light-damaged DNA. Repair synthesis of DNA damaged by ei...

We have developed in detail the theory of X-ray line and continuum production due to atomic interactions of accelerated ions, incorporating in our calculations information from a broad range of laboratory measurements. We applied our calculations to the Orion region from which nuclear gamma-ray lines were observed with the COMPTEL instrument on CGRO. The accelerated particles which produce this...

MeV gamma-rays provide a unique window for the direct measurement of line emissions from radioisotopes, but observations have made little significant progress after COMPTEL/{\it CGRO}. To observe celestial objects in this band, we are developing an electron-tracking Compton camera (ETCC), which realizes both bijective imaging spectroscopy and efficient background reduction gleaned recoil electr...

Background: Lymphocytes of Fanconi anemia (FA) show an increased sensitivity to the alkylating agents such as mitomycin C (MMC), but their responses to gamma-irradiation is controversial. The extent of DNA damage in leukocytes of FA patients following irradiation and MMC treatment was studied at cellular and single chromosome level. Methods: DNA damage induced by gamma-rays and MMC was measure...
