１ρ（が用いられていた。[Prior Art] It is widely practiced to irradiate the human body with radiation rays such as X-rays, gamma rays, beta rays, and electron beams for diagnosis and treatment of diseases. In this case, a filter is usually installed between the irradiation device and the human body, and the radiation line -+t'(#
A so-called compensation filter is used to compensate for E and radiation quality to accurately irradiate or diagnose specific organs, blood vessels, etc. Conventionally, lead glass, barge resin, barge rubber, aluminum metal, and silver/gold 1ρ have been used as materials for this filter.

Moreover, it is necessary to perform fine M adjustment of such filters on a case-by-case basis in hospitals, etc., but conventionally used filters made of the above-mentioned materials have not been able to sufficiently meet such demands. That is, 1
)? Filters using gold metal lead glass or barge acrylic resin have sufficient strength, but are inferior in flexibility, are difficult to finely adjust the radiation absorption ability, and cannot be cut easily. inferior to sex. Although gold ore rubber filters are flexible, they require a vulcanization operation, and it is not easy to fine-tune the compensation ability. Furthermore, although the above-mentioned conventional filter material has been conventionally used as a radiation protector, it also has the drawback of a narrow compensation range.

(Published in Japan), lipiotol, ultraviolet coagulable polymer,
It is described that filter materials mixed with iodine compounds such as urographin and angiographin are used as filter materials.
