Detectors for Radiation DosimetryIn previous years Radiation Dosimetry in Medicine was concerned mainly with measuring doses produced by x-rays, gamma rays and electrons. These radiations have the common feature that their R.B.E. ≈ 1, and they can be monitored by the same types of detectors.

Passive DetectorsIn this lecture I shall interpret the term “passive” radiation detector as meaning one that will yield up its information after an irradiation is completed, and often only after some processing of the detector to obtain the data or some considerable data processing. Examples of such detectors would thus be:

Olli Haavisto,Heikki HyötyniemiThis is due in part to the similar atomic composition of soft tissue tumors and normal surrounding tissue. Prior to CT x-ray imaging, the presence of large abdominal masses was frequently determined by the extent of distortion and displacement of adjacent anatomical structures filled with contrast media rather than by direct imaging of the mass.

Biological Effects of Radiation and Their Variation with Radiation Qualitydies and I should warn you right from the start that in my lecture you will not find the latest details but generalities, because I will deliberately insist on the formulation of problems rather than pointing to their possible solutions in the different instances.

Omid Bozorg-Haddad,Babak Zolghadr-Aslies. Because of the wide scope of such risk analytic investigations, in one lecture it will only be possible to give you some impression of the complexity of this topic and of concepts to cope with it, rather than a thorough discussion of our present knowledge.

Marius George Linguraru,Ronald M. Summersg relatively large objects to high-LET radiation with a relatively uniform absorbed dose distribution throughout the subject. In addition, neutrons from certain sources, e.g., fission reactors, provide large fields for the irradiation of many biological objects at a time, an essential feature for the study of effects in animal populations.
