A novel evaluation technique for radiochromic films based on cosine-distance analysis: Feasibilities of wide range photon dosimetry and postal intercomparison in lieu of conventional TLD chips

Photon radiation induced decolourisation of radiochromic film changes its optical density. The photon dose is thereby evaluated as a function of optical density. The detection limit of common radiochromic films lies between 1 cGy and 20 Gy. This paper describes a novel evaluation method of radiochro...
