A deliberation to the effectiveness of the NORM guideline

NORM stands for Naturally Occurring Radioactive Material. The existence of NORM as consumer products in our living-environment probably raises the opportunity of radiation exposure of us. In Japan radioisotopes are exempted by the criteria in quantity and concentration by the Law Concerning Prevention of Radiation Hazards based on the International Basic Safety Standards (BSS). Furthermore when the RI are naturally occurring radioactive materials without extraction from ores their quantity and concentration are limited by the law of the Nuclear Reactor and Fuel Regulation Law. Moreover “Guideline for Ensuring Safety of Raw Materials and Products Containing Uranium or Thorium” (Guideline) was taken effect in June 2009. By the Guideline an argument of “justification” of the radio-protection is not accomplished. Furthermore whether the security from the useless radiation exposure in our living-environment can be secured by the Guideline is doubt. By comparing the effectiveness of the Guideline with the law of other countries the issues of regulations of Japan to NORM are deliberated in this paper.
