We oppose ICRP exposure standards of “less than 1 millisievert per year” as “aiming at about 1 millisievert per year”.
In the first place, "1 millisievert per year" is related to external exposure, and internal exposure is not considered.
In consideration of this, the European Commission on Radiation Risk (ECRR) has recommended that "Do not exceed 0.1 mSv / year".
The standard value should not be set because it is difficult to evacuate or because there are no financial resources.
