Ionizing Radiation and the dose is small The effects of irradiation on living systems may be studied by looking for effects on the living cells, for changes m the biochemical reactions, for evidence of production of dis ease, or for changes m the life or normal growth patterns (Fig 44-4) Interpretation of such findings is not simple Extensive research m this field is continually being earned out in many laboratories The human body is composed largely of water and of other materials containing hy drogen, carbon, oxygen, nitrogen, and smaller amounts of other elements In human tissue, these elements are present in the proportion of about one nitrogen atom to twenty oxygen, to five carbon, and to forty-five hydrogen atoms It is therefore important to study the effects of radiation on water and on ma terials of a composition which resemble human bssue Irradiation of water produces large num bers of free electrons which have been ejected from the parent atoms, leaving positive ions In this process of ionization, there is dissocia tion of the water molecule and the release of oxidizing agents In the human body, there may be changes of structure of organic mole cules and changes in the biochemical proc esses Some of these same changes may be occurring independently of the radiation, so the mechanisms are complex and are being studied intensively Types of injuries The accumulation of knowledge of the effects of radiation on man was begun in 1895 when Roentgen discovered the X ray Radiation from uranium was discovered by Becquerel m 1896 Alpha, beta, and gamma rays were identified shortly thereafter, and the neutron was discovered m 1930 Injuri ous effects were experienced by these early workers m nuclear science As radiation was applied to man for healing purposes, effects such as skin redness, dermatitis, and skin cancer were noted, as were loss of hair and eye inflammation It was found that the incidence of cancer and of certain blood dis eases was higher among radiologists than would be expected for a chance distribution in the population studied The pool of health experience data was obtained from (a) early radiation workers.
