Ionizing radiations produce deleterious effects in the living organisms and the rapid technological advancement has increased human exposure to ionizing radiations enormously. There is a need to protect humans against such effects of ionizing radiation. Attempts to protect against the deleterious effects of ionizing radiations by pharmacological intervention were made as early as 1949 and effor...

Ionizing radiations resulting from radioactive materials have widely uses in many applications various

I have read with great concern the article written by Borém et al. (1) – " The knowledge about diagnostic imaging methods among primary care and medical emergency physicians " –, published by Radiologia Brasileira in December/2013. The presented results show in a hard-hitting way that physicians are educated even without an appropriate idea about what is ionizing radiation, radiological imaging...

Health effects caused by ionizing radiations raise considerable concern among general public and radiation workers. To estimate ability of personal protective equipment (PPE) materials that reduce toxic effects of ionizing radiations, we developed an experimental bioassay system using Chinese Hamster V79 cells. The system developed here distinguished the biological effectiveness of X-ray that w...

INCE 1927 numerous investigators have subjected various plants and animals to radiations of different ion density to determine the relative biological effectiveness (RBE) of the different radiations. Usually it was found that the RBE increased as the linear energy transfer (LET-energy in electron volts dissipated per micron of tissue traversed by ionizing particles) or ion density of the radiat...
