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

Luminescent minerals within ceramic building materials have been successfully applied as surrogate dosimetry materials to important dose reconstruction studies, in particular at Hiroshima and Nagasaki, and more recently in areas affected by radioactive fallout (e.g. the Nevada Test Site, the Chernobyl accident, the Semipalatinsk Nuclear Test Site, Chelyabinsk, etc.).  These retrospective studies aimed to reconstruct the cumulative gamma dose years after the onset of the contamination event. Recent concerns regarding future radiological emergencies has led to widening the search for other surrogate dosimetry materials that can be used on a much shorter timescale. In this lecture we examine the range of materials and techniques that are potentially available for dosimetry investigations on long and short timescales and include practical aspects of their application.

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

Space is much complicated radiation field due to the mixture of various high energetic charged particles. These primary particles additionally produce various secondary particles via nuclear interactions with materials. The measurement of linear energy transfer of charged particles is essential to assess the dose equivalent in space. The lecture will present about the space radiation environment and its dosimetry.

Abstract

Microdosimetry is a chapter of the radiation physics. It gives a full theoretical description of the energy absorbed in a finite site caused by a single radiation event. When the site size is comparable with biological structures, microdosimetry physical quantities describe the first step of events that give eventually rise to the biological effect. Microdosimetry is nowadays the best heuristic tool to assess the biological effect of a mixed radiation field without direct biological measurements.
The lecture syllabus: i) historical background; ii) scientific background; iii) microdosimetric quantities; iv) microdosimetric detectors; v) microdosimetry for BNCT; and vi) microdosimetry for ion radiotherapy.

Abstract

The tremendous success of the use of ionizing radiation in medicine has resulted in medical exposures becoming one of the largest contributors to radiation exposure of humans. As such, dosimetry is essential to quantify exposure to patients, staff and the public. Solid-state dosimetry (SSD) has many advantages for this including the wide range of doses that can be detected as well as small detector size and potentially fast read-out. The lecture will include a broad introduction in the use of ionizing radiation in medicine focusing on advanced applications. Solid-state detectors and dosimeters will be contrasted with other dosimeters widely used in medical applications and an attempt made to predict the role of SSD in medicine over the next 10 years.

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.
