Radiation dosimetry.

This article summarizes the basic facts about the measurement of ionizing radiation, usually referred to as radiation dosimetry. The article defines the common radiation quantities and units; gives typical levels of natural radiation and medical exposures; and describes the most important biological effects of radiation and the methods used to measure radiation. Finally, a proposal is made for ...

Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation

A new method for tooth (enamel and dentine) and bone EPR dosimetry is proposed that enhances substantially the dosimetric sensitivity. The method is based on the nonstandard spectra registration mode (the second harmonic phase quadrature detection of absorption under rapid passage conditions). This method provides an apparent enhancement of the component ratio of radiation to a nonradiative bac...

Principles of Radiation Dosimetry

students derive much benefit from a book of this type. As a supplement to their standard texts it not only aids them in understanding structure but stimulates their studying of anatomy by integrating physiology and emphasizing the practical application of such knowledge. A book of this type allows a busy physician to review in a short time the essentials of normal anatomy of various structures ...
