Quantities for Use in Radiation Protection-A Comment on Quantities Proposed in ICRP 1990 Recommendations.

The new ICRP memorandum and quantities in radiation protection dosimetry.

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...

Comment on "The illusion of invariant quantities in life histories".

Nee et al. (Reports, 19 August 2005, p. 1236) used a null model to argue that life history invariants are illusions. We show that their results are largely inconsequential for life history theory because the authors confound two definitions of invariance, and rigorous analysis of their null model demonstrates that it does not match observed data.

Radiation protection of the eye lens in medical workers—basis and impact of the ICRP recommendations

The aim of this article was to explore the evidence for the revised European Union basic safety standard (BSS) radiation dose limits to the lens of the eye, in the context of medical occupational radiation exposures. Publications in the open literature have been reviewed in order to draw conclusions on the exposure profiles and doses received by medical radiation workers and to bring together t...
