DEVICE TO MEASURE DOSE OF IONISING RADIATIONS Russian patent published in 2012 - IPC B32B27/32 G01T1/02 

FIELD: measurement equipment.

SUBSTANCE: invention relates to equipment, namely, to devices for measurement of a dose of low-energy ionising radiation in open space during orbital flights of aircrafts around the Earth. A device to measure ionising radiation comprises a metal vessel, which holds sensitive elements. A device vessel is a truncated cone with an angle of cone opening equal to 90°±5°. At the side of the smaller base of the truncated cone there is an inlet window for sensitive elements protected at the side of the inlet window with a polyethylene terephthalate metallised film. At the side of a larger base of the truncated cone there is a cover fixed with a threaded rod element arranged on it.

EFFECT: making it possible to measure a dose of ionising radiation in open space behind a minimum protection of 5·10^-4 g/cm² with isotropic sensitivity of each dosimeter inside a model for this solid angle in the range from 0 to 2π steradian.
