Abstract

The basic concepts of radiation dosimetry are reviewed. The dosimetric quantities, kerma, absorbed dose and exposure together with the relations between them are discussed in depth. Finally it is indicated how the absorbed dose can be measured with a calorimeter by measuring the temperature increase and with an ionisation chamber measuring the charge produced by the ionizing radiation and making use of the Bragg-Gray relation.

Abstract

When you encounter an accident/incident/anomaly associated with radiation exposure, it is crucial to immediately identify the individuals who received significant exposure levels, estimate their doses quickly (even roughly) and make it possible to provide the best medical treatment on a case-by-case basis. The lecture will present a practical guide to achieve the most appropriate dosimetry in such emergency situations.

Abstract

Luminescence remains one of the most widely used phenomenon in passive radiation dosimetry. The related techniques, thermoluminescence (TL), optically stimulated luminescence (OSL) and radiophotoluminescence (RPL), are the basis of successful commercial dosimetry systems. In this lecture we will explore the unifying principles behind these techniques, explore advantages and disadvantages of each one of them, and discuss the state of the art. The topic will also provide the fundamentals for other lectures in the School.

Abstract

Heavy charge particle dosimetry and especially dosimetry of neutrons present multiple challenges and are the most difficult tasks in radiation detection. The first challenge is associated with strong dependence of most detectors on particles energy and LET. The second big challenge is caused by presence of photons in most radiation fields. The lecture will cover several particle detection techniques and will focus mostly on technologies capable of detection, visualization and spectroscopy of individual particle tracks. Fluorescent Nuclear Track Detectors (FNTD)are the latest advancement in this growing field.

Abstract

Occupational exposed workers are subject to dosimetric control. In most countries, passive dosimetry systems are used to verify compliance with regulatory dose limits. Active personal dosemeters (APD) are frequently used as alarm dosemeters in potential high dose areas, and help in the application of the ALARA principle.  The basic objective of a personal dosemeter is to provide a reliable measurement of the operational quantities Hp(0.07), Hp(3) and Hp(10) for all practical situations, independent of the type, energy and direction of the radiation, and with a prescribed overall accuracy. For some installations, passive environmental dosimetry is also needed, e.g. to control exposures at boundaries of installations, where the quantity H*(10) needs to be measured. In this lecture, different types of personal and environmental dosemeters will be reviewed.
