摘要：1,188,933. Dosimeter. SCIENCE RESEARCH COUNCIL. 22 Nov., 1967 [22 Aug., 1966], No. 37438/66. Heading H5R. A dosimeter comprises a container having a substantially constant volume under the conditions of measurement employed, a solid material within the container, which material when irradiated by the radiation to be measured, evolves a gas in a quantity related to the radiation dose and means to indicate the pressure within the container. The material exemplified is polyethylene in the form of a powder or as a thin film, e.g. 0À003 inch in thickness, the film being inserted in the container as a roll. The pressure indicating means may be a Bourdon gauge communicating with the interior of the chamber, or the container may be closed and the pressure be indicated by a strain gauge associated with the wall of the container. As a variant on this alternative, one wall of the chamber may be constituted by a diaphragm and movement of this diaphragm may be used to indicate the pressure in the container.
