Radiation Protection among Radiation Workers in Teaching Hospital.

Mmenyene M. Usen, Glory V. Umoh


Radiation protection entails the harmful effect of ionizing radiation, the interaction of any amount of ionizing radiation of any type, such as X-rays, gamma rays, electrons, protons, neutrons, alpha particles and beta particles with a biological system results in the absorption of the energy of the radiation by the system. This in turn may result in effects that become manifest in the exposed individuals (somatic effects) or appear in the descendant of exposed individuals (Genetic or Hereditary effects). The physics of the absorption process is over in 10-16 seconds, the chemistry takes longer, since the life time of the free radical is about 10-6 seconds, the biology takes days to months for cell killing, years for carcinogenesis, and generations for heredity damage. Available information on human susceptibility to effects of ionizing radiations has it that the lethal dose for 50% of the exposed population to die within thirty days of exposure is about three gray, for whole body exposure. Some organs and tissues are more sensitive to radiation and some are less. More sensitive tissues are blood forming organs, reproductive organs are those that constitute the nervous system. Death of a person may result from the overall exposure of the body for the destruction of vital organs. Acute exposure and chronic exposure at equal total doses may or may not produce the same effects.
