Several kinds of hydrophobic coatings were tested on concrete and epoxy samples. These samples were exposed to 740–1110Bq/cm3 of HTO vapor at 1kPa pressure at 288–298K for 1–60weeks. Static leaching tests on HTO absorbed samples were conducted in distilled water, and the leaching was evaluated as a...
