An experimental study on a radiochromic film (ISP type MD 55) was carried out to assess the most important features of this detector at the Co- 60 gamma-ray quality. The investigated characteristics were the absorption spectrum in the wavelength range 600 nm + 700 nm, the linearity of the absorbance with absorbed dose, the repeatability, the reproducibility, the post-irradiation stability, the dependence of the absorbance on temperature during readout. A particular readout procedure was studied in order to obtain by a Cary I spectrophotometer a repeatability of about 0.5%. The results obtained indicate that using this dosimeter, absorbed dose determinations can be performed with an uncertainty not exceeding 3% (1σ).
