Wide-angle free-air chambers (WAFACs) are used as primary standard measurement devices for establishing the air-kerma strength of low-energy, low-dose rate brachytherapy seeds. The National Research Council of Canada (NRC) is commissioning a primary

The authors of a recent paper (McNiven et al 2008 Phys. Med. Biol. 53 5029-43) measured the volume of a particular type of a small ionization chamber using CT images. Using four Exradin A1SL chambers, they find that the volume measured using CT imagi

The authors of a recent paper (Claridge Mackonis et al 2007 Phys. Med. Biol. 52 5469–82) measured cell survival in spatially modulated radiation fields. They claim to have identified two new types of radiation-induced bystander effect. We conclude

To model the transport of electrons through material requires knowledge of how the electrons lose energy and scatter. Theoretical models are used to describe electron energy loss and scatter and these models are supported by a limited amount of measu

This in vitro study was undertaken to determine if ultrahigh dose rates could improve the radiation response of human tumors. Two cell lines, human glioma (U-87 MG), which is radioresistant, and human melanoma (HT-144), which is radiosensitive, were

The principal objective of the authors' measurements was to determine the effect on ionization chamber response of a 0.3 mm thick nylon sleeve (as used at the NRC) and of a 1 mm Lucite sleeve (as used at the PTB). They estimated that with 60Co, the n
