SUPPORT SUBSTRATE FOR RADIOISOTOPE PRODUCTION, TARGET PLATE FOR RADIOISOTOPE PRODUCTION, AND PRODUCTION METHOD FOR SUPPORT SUBSTRATE

摘要

Provided is a target plate for radioisotope production that has sufficient durability and sufficient heat resistance for use in radioisotope production and that is capable of reducing the extent of radioactivation. In a target plate (10) for radioisotope production, a support substrate (2), which supports a target (1), includes a graphite film(s). The thermal conductivity in a surface direction of the graphite film(s) is 1200 W/(m·K) or greater, and the thickness of the graphite film(s) is 0.05 µm or greater and 100 µm or less.
