Descriere referat:

ABSTRACT: The radiatios and the natural radioactivity have always made part of the environment, but because of the absence of their impact on human’s senses, they have relatively late took the attention of scientists. From the radiations and the radioactive materials, by now, several applications concerning the radionuclides properties were introduced and also new technologies were created, the result of all these being the radioactive products wanted or not. In consequence any person on the Earth is permanently submitted to the radiations activity which proceed from both natural and artificial sources. In these terms any protection system against radiations must have a well defined domain. The estimation of doses recived from every source is a permanent preoccupation of some international and n national organizations.
