This chapter examines the interaction of various radiations with matter beginning at the atomic level and finally at the macroscopic level. Incident electrons, beta particles and heavy ions are stopped primarily by the orbital electrons through Coulombic interactions. Additionally, electrons and betas can produce bremsstrahlung. Heavy charged particles

Continuous radiation — Scattered radiation
1970A The continuous radiation from an X-ray tube is scattered by the sample, diffracted by the analyzing crystal and measured by the detector.

Nature, 1960
A discussion is presented of the view that whole-body irradiation of an animal can, in certain circumstances, speed up natural aging. In survival studies of chronically irradiated CBA mice, kept under certain conditions so that external disturbing factors were minimized, mean life shortening of a group of mice is roughly proportional to the mean ...

Radiation Protection Dosimetry, 2011
When this paper was about to go to press, the International Commission on Radiological Protection released a statement recommending a change in the threshold dose for the eye lens and dose limits for eye for occupationally exposed persons. It is clear that the earlier published threshold for radiation cataract is no longer valid.

Radiology, 1954
The field of radiation dosimetry involves a close relationship between units and instrumentation that is similar to the proverbial chicken and egg relationship, in which it is difficult to state unequivocally which came first. This duality has had a profound influence on the historical development of the field. It also justifies the presentation of the

Microdosimetry and radiation quality determinations in radiation protection and radiation therapy
Radiation Protection Dosimetry, 2011Beams of different radiation qualities may, for equal absorbed dose, lead to important differences in the degree of harm for a specific biological endpoint. In many practical situations absorbed dose is then not a sufficient measure when for instance the same treatment result or risk level is the focus of attention.

RADIATION BIOLOGY: CONCEPTS FOR RADIATION PROTECTION
Health Physics, 2004The opportunity to write a historical review of the field of radiation biology allows for the viewing of the development and maturity of a field of study, thereby being able to provide the appropriate context for the earlier years of research and its findings.

Publisher Summary This chapter describes the important features of a few popular types of detectors. Most of them are based on the ionization produced by radiation, with the resulting currents passing through an electrical circuit and displayed on a meter or similar indicator.
