FIELD: physics.
SUBSTANCE: viewing radiation protective window includes metal case of double-glazed window. The double-glazed window is located in it. Last consists of several blocks of glass plates. Each of blocks consists of the case. At least one glass plate is located in the case. It is executed from the glass containing SiO2, K2O, PbO and CeO2. The radiation-protective window in addition contains liquid block. Last is supplied by viewing glasses, filled by an immersion-protective fluid and joined to the double-glazed window case. The glass of the glass plates in addition contains P2O5, BrO3, Al2O3, BaO, Sb2O3 and Nb2O5. The Immersion-protective liquid represents composition from dimethyl sulfoxide, nitrate of lead, water and formamide.
EFFECT: increase of radiation-optical stability passing abilities in visible field of spectrum, radiation-protective properties and total weight decrease.
