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...

This paper describes the mechanisms of action of ionizing radiations combined with antineoplastic drugs. Some relevant drugs for the combined modality treatments of locally advanced lung cancer are reported. The meta-analyses including randomized trials comparing single agent (radiotherapy or chemotherapy) versus combined chemotherapy and radiotherapy in patients with unresectable non small cel...

Numerous and extensive investigations have been conducted on the influence of ionizing radiations on pure cultures of microorganisms. Various aspects of such research have been subject of a rather comprehensive review by Rayman and Byrne (1957). In contrast to pure culture studies, the present report deals with the influence of gamma radiation on several of the microbial groups present in the h...

1.1 Ionizing radiation Human exposure to ionizing radiation is a natural part of life on earth. These exposures occur every day from radiation associated with naturally occurring radionuclides in soil, air, and food, and also from cosmic rays. In addition, many people are exposed to dental and medical diagnostic procedures and therapy involving: x rays, gamma rays, charged particles, radionucli...
