sources and effects of ionizing radiation
TL;DR: This annex is aimed at providing a sound basis for conclusions regarding the number of significant radiation accidents that have occurred, the corresponding levels of radiation exposures and numbers of deaths and injuries, and the general trends for various practices, in the context of the Committee's overall evaluations of the levels and effects of exposure to ionizing radiation.

Fifty years of Monte Carlo simulations for medical physics.
TL;DR: The history of the correction for wall attenuation and scatter in an ion chamber is presented as it demonstrates the interplay between a specific problem and the development of tools to solve the problem which in turn leads to applications in other areas.

TL;DR: The study confirms that EBT3 film can be used for clinical practice in the same way as the previous EBT2 film, and shows that the orientation dependence with respect to film side is completely eliminated.

Radiochromic film dosimetry: Past, present, and future
TL;DR: Development of GAFCHROMIC™ film models through improvement in their sensitivity and uniformity as two dimensional detectors and future directions in development of this important dosimetric tool revolving around its possible use as a three-dimensional dosimeter and the energy dependence of the film's response are summarized.

AAPM's TG-51 protocol for clinical reference dosimetry of high-energy photon and electron beams.
P. R. Almond,Peter J. Biggs,Bert M. Coursey,William F. Hanson,M. Saiful Huq,Ravinder Nath,David W. O. Rogers +6 more
TL;DR: This protocol represents a major simplification compared to the AAPM's TG-21 protocol in the sense that large tables of stopping-power ratios and mass-energy absorption coefficients are not needed and the user does not need to calculate any theoretical dosimetry factors.
