The possibility of application flexible infrared Nanopolycrystalline (PIR) fibers made from radiation-resistant crystal systems AgBr – TlI and AgBr – TlBr 0.46 I 0.54 , for contact-less measure temperature bearings of own needs mechanisms and signal temperature transmission from nuclear power plant containment is considered. Radiation resistant allows the use that crystals and PIR fibers in high radiation conditions up to 500 kGy, what opens great opportunities of involving that optical materials in atomics. The class of the presented materials is distinguished by a wide transmission range in the range from 0.4 to 60 µm for crystals and from 2.0 to 25 µm for PIR fibers without absorption window, low optical loss (up to 0,1 dB/m), high flexible. The PIR fibers proposed in this paper are made by extrusion from single crystals of silver and thallium halides and are transparent in the mid-infrared range from 2 to 25 µm, which, according to the laws of Planck and Wien, corresponds to temperatures from +1100 °C to –200 °C.
