Recent Discussion on Protection Quantities and Operational Quantities by ICRP and ICRU

The new ICRP memorandum and quantities in radiation protection dosimetry.

21/110/05 DRAFT FOR DISCUSSION INTERNATIONAL COMMISSION ON RADIOLOGICAL PROTECTION COMMITTEE 2 BASIS FOR DOSIMETRIC QUANTITIES USED IN RADIOLOGICAL PROTECTION Task Group of ICRP Committee 2:

Operational quantities derived from the norm and generalized Fredholm theory

We introduce and study some operational quantities associated to a space ideal A. These quantities are used to define generalized semi-Fredholm operators associated to A, and the corresponding perturbation classes which extend the strictly singular and strictly cosingular operators, and we study the generalized Fredholm theory obtained in this way. Finally we present some examples and show that...

A Discussion about Representation Models for Imprecise Quantities and Probabilities

Radiation Quantities and Units

The unique radiation exposure conditions that exist in computed tomography (CT), during which thin slices of the patient are irradiated by a narrow, fan-shaped beam of x rays emitted from the x-ray tube during its rotation around the patient, have required the use of special dosimetry techniques to characterize the radiation doses to patients and to monitor CT system performance. This section d...
