Evaluation of doses related to ionizing radiations sources: means and uncertainties

A. Rannou. Indoor+Built Environment 10, 332-338, 2001

People are exposed to several types of ionizing radiation from both natural and man-made sources. A set of concepts and dosimetric quantities, along with approximations or models may be used to evaluate doses from these sources of radiation whatever they are and whatever their form or the energy and intensity of radiation. This scheme is considered to provide reliable results for the purposes of protection against radiation. However, some limitations are also illustrated which account for the various and complex mechanisms which intervene in the real situation of exposure to radiation.
