Dosimetry with radiochromic films: a document scanner technique, neutron response, applications.
The possibility of reading radiochromic films by the employment of a document scanner and associated software was explored. Dosimetric characteristics, such as the sensitivity of the technique, reproducibility in dose assessment, minimum detectable dose, film uniformity, OD variation with time, variation of OD due to multiple scans, polarity of the analyzing light, fast neutron response and thermal neutron yield were investigated. The technique was used to measure dose distributions in stereotactic radiotherapy, orthovoltage treatment and neutron capture therapy.
