The films were characterised by means of Raman/photoluminescence/FTIR spectroscopy, XRD, RBS and elastic recoil detection analysis (ERDA). Thermoluminescent (TL) responses of these materials to photons provided by radionuclide Fe-55 source (approximate to6 keV) over the dose range from 1 to 100 mGy were measured. Typical TL glow curve is a result of two components, one with maximum in range 160-180 degreesC and the second, between 307-327 degreesC. In irradiated samples, the first peak is caused by the exposure to daylight, which increases overall TL signal, the second is caused by irradiation by gamma-photons. Exploitation of TL properties of CVD diamonds for a photon dosimetry is possible after careful daylight shielding. The sensitivity of used CVD diamond dosimeters was 10 times less than that of TLD 100 (LiF: Mg, Ti) Harshaw dosimeter.
