 Abstract

Current radiation protection is a very sophisticated and elaborate domain where, once the information about the exposure of persons is known in terms of the quantity of the effective dose, we can predict resulting radiological consequences related to the stochastic risk to the health of the exposed persons without a need for other details. In fact, the effective dose contains all pertinent information including the average organ dose distribution and relevant radiation and tissue weighting factors which take into account the specific effects of different types of radiation and selected tissue radiosensitivity. Since the effective dose cannot be measured directly, one has to rely on the monitoring of other appropriate measurable quantities and then do some conversions. The current structure of radiation protection quantities includes too many quantities, the definitions of some of which are not easy to understand and interpret. Moreover, there are numerous quantities based on the dose equivalent, such as the equivalent dose, effective dose, committed equivalent dose, committed effective dose, collective equivalent dose, collective effective dose, personal dose equivalent, ambient dose equivalent and directional dose equivalent, where the only unit of Sv is used. There are a number of cases in open literature reflecting the difficulties and mistakes in the use of radiation protection quantities. Even more complicated situations are encountered in the field, where the staff responsible for personal and workplace monitoring is confused because of so many different quantities and where the staff may not be qualified and experienced enough to be able to make the relevant conversions and interpretations. The paper summarizes our experience in teaching students and lecturing in various training courses addressing radiation protection where the primary task was to ensure that all radiation protection personnel understood the quantities and units used in radiation protection in the correct way consistent with their latest definitions and ICRP recommendations. The substance of the paper may be useful to those who are not specialists in the field but it is important for them to understand principal objectives and current requirements of radiation protection.
