Chronic radiation sickness

Chronic radiation sickness occurs as a result of long influence of low doses of ionizing radiation and is characterized by the gradual development and long wavy course, reflecting the combination of a slowly progressive deterioration effects signs of recovery processes. Relatively little damage caused by ionization, long offset reparative processes, but as cumulation alternative processes begin to outweigh the regeneration.
Outcome of chronic radiation sickness, developing the uniform irradiation of the body are abrupt suppression of hematopoiesis, bloody diates, reducing resistance of the vascular walls, bleeding in tissues and organs, infectious complications, and other
One of the main pathogenetic features of chronic radiation sickness arising from the radioactive substances with the election distribution or at external exposure to ionizing radiation is the early development of human activities so-called critical of the authorities due to their special radiosensitivity or preferential accumulation in them of the radioisotope. For example, when ingested radioactive iodine critical organ is the thyroid gland, with external irradiation one of the critical organs is the bone marrow.
Clinical manifestations of individual periods of the disease in chronic radiation sickness expressed weakly. Throughout diseases is dominated by local changes.
In the study of the corpses of people who have died from exposure to radiant energy, medical personnel must observe the special safety measures. Mandatory dosimetric control, which is not only a safety precaution, but sometimes an important diagnostic technique for detecting incorporated radioactive substances.
