Radiation Units, Limits and Dose Constraints

Y. Lemoigne and A. Caner (eds.), Radiation Protection in Medical Physics, NATO Science for Peace and Security Series B: Physics and Biophysics 1, DOI 10.1007/978-94-007-0247-9_2, © Springer Science+Business Media B.V. 2011 Abstract A number of radiation units exist for representing radiation dose to patients, staff, public and quantities for radiation equipment performance in radiological pract...

Evaluation of the annual effective dose to Cath Lab staff in the Afshar Hospital, Yazd and suggesting the radiation protection strategies to better management of occupational dose

Introduction Due to the increasing use of angiography procedures and the higher risk of deterministic and stochastic effects for radiation workers of these sections than other radiological procedures, radiation safety is very important in angiography staff. So, this study aimed to obtain the effective dose of angiography staff and compare them with the standard dose limit and finally outline th...

Radiation-induced apoptosis: effects of cell age and dose fractionation.

The cell cycle dependence of radiation-induced apoptosis was measured using mitotically synchronized REC:myc(ch1) and Rat1:mycb cells. Cells in S and G2 phases were more susceptible; the apoptotic fraction was about 0.7-0.8 as compared to about 0.4 for G1 cells at a dose of 10 Gy. Two-dimensional cytofluorimetric analysis of cells, pulsed-labeled with bromodeoxyuridine and then irradiated with ...

Dose fractionation in synchrotron radiation x-ray phase micro-tomography.

Phase sensitive x-ray imaging expands the applicability of standard attenuation based techniques by offering several orders of magnitude of increase in sensitivity. Due to the short wavelength, x-ray phase is not directly measurable, but has to be put in evidence by the use of phase contrast techniques. The phase can then be reconstructed from one or several phase contrast images. In this study...

The relevance of occupational epidemiology to radiation protection standards.

Large-scale epidemiological studies of U.S. Department of Energy workers have been underway since the 1960s. Despite the increasing availability of information about long-term follow-up of badge-monitored nuclear workers, standard-setting bodies continue to rely on the Life Span Study (LSS) of A-bomb survivors as the primary epidemiological basis for making judgments about hazards of low-level ...
