Study on Surface Pressure of High-Pressure Water.

Abstract

Radioactive pollution spreads through roofs and gardens around Hamadori district and Nakadori district of Fukushima Prefecture by the Fukushima Daiich nuclear disaster, so various decontamination methods are examined.Using high pressure-water is one of decontamination methods that is effective for reduction of radiation dose rate.Authers thought that pressure of high pressure-water influences on reduction of the radiation dose rate, so we investigated influence of washing machines, nozzles, and washing distance on washing pressure in this report.In addition, we considered about the influence of washing condition on washing power.
