This article describes apparatus for quickly checking the positioning and dwell times of a high-doserate (HDR) afterloader as part of daily quality assurance (QA). A groove was milled into an aluminum plate to align an HDR applicator, and fluorescent screens were placed on either side of the groove.
## Aim: The aim of this work was to assess the suitability of the use of a gafchromic ebt2 film for the measurement of anisotropy function for microselectron hdr (192)ir (classic) source with a comparative dosimetry method using a gafchromic ebt2 film and thermoluminescence dosimeters (tlds). ## B
