Introduction: Gamma radiations have used frequently at medical radiation centers for treatment of different cancers. This study aimed to consider possible alterations in level of serum zinc and selenium among nuclear medicine staff. Materials and Methods: This cross sectional study was carried out on 30 nuclear medicine staff and 10 individuals as control gr...

The virulence of C. albicans is associated with the transitional evolution from yeast to filamentous forms. We were interested in the effects amphotericin B (AMB), ketoconazole (KTC) and gamma-radiations might have on these broadly defined phenotypes as determined by the CFU procedure. By using collagen gel as the 3-dimensional support of cell culture, diverse experimental conditions were conte...

The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...

ARLY investigators in radiation genetics claimed that X-rays of different wave E lengths, gamma rays, and beta particles of radium were equally effective in inducing sex-linked recessive mutations in Drosophila melanogaster and that densely ionizing radiations such as recoil protons from neutrons and alpha particles were less efficient than the less densely ionizing X, gamma, and beta radiation...

abstract background and purpose: people are always exposed to ionizing radiation, which could badly influence their health. the degree of these influences depends on the level of radiations. in this study the dose of indoor gamma radiation was assessed using rds-110 multi-purpose survey meter. materials and methods: to determine the dose rate of indoor radiations in cities of hamedan province f...

Survival curves for biological cells irradiated with gamma rays (and other low LET radiations) cannot be properly interpreted without examining the implications of these interpretations for high LET radiations. The theory of RBE demands that the RBE of any high LET radiation field is at most one when the probability for cell killing as a function of the absorbed dose of gamma rays is linear or ...

Induced mutation study was carried out to study effect of chemical and physical mutagens on different morphological characteristics in the Brassica napus L. cv. Excel. Physiologically similar and uniform size seeds of Brassica napus L. cv. Excel weretreated with different doses of chemical Ethyl methane sulphonate (EMS) and Sodium azide (SA) andphysical mutagen (gamma radiations). Dry and pre-s...
