Maximum Permissible Doses,its inception, the ICRP has been the one internationally recognized body responsible for recommending values of maximum permissible exposure to ionizing radiation. Most of the national legislation relating to exposure to radiation is based on the recommendations of the ICRP.

Radiological Emergencies,ng from a minor laboratory spill involving a few MBq of radioactive solution up to a major reactor accident in which many thousands of TBq of fission products may be released. Basically an emergency can arise because of:

Die Wiederkehr des autoritären Charakterssorbing medium. The source of nuclear radiation may be radioactive atoms or equipment such as X-ray machines. The effect of absorbing the more familiar types of radiation, such as heat, is to raise the temperature of the absorbing medium. If this medium is the human body, or part of it, the rise in

The nature and severity of these symptoms and the time at which they appear depend on the amount of radiation absorbed and the rate at which it is received. Radiation injuries can be divided into two classes

,Die Kausalität in der gegenwärtigen Physik,roblem. It has been estimated that the total quantity of radioactivity in use in research and medicine in 1938 was less than 30 TBq, corresponding to about 1 kg of radium derived from natural sources. Today, a single large power generating reactor may contain in excess of 10. TBq of fission products
