Dosimetry film

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The primary aims of this thesis are: A) to measure the dependence of the DAPR20,10 on the size of the primary small photon field, and to relate this data to TPR20,10 of the reference field. B) to develop a method of using a large-area ionization chamber to compare the measured dosearea product to that calculated by a treatment planning system. C) To gain further understanding of the dose-area product by supplementing the results with 2D high resolution film dosimetry.

Dosimetry is of crucial importance in radiation processing of food. Among others, plastic film has been widely used for dosimetry in radiation therapy since its density is quite similar to the equivalent biological materials. In this study, the depth dose distribution was estimated by using gafchromic film for the purpose of dosimetry in food irradiation.
