- 1/12 of the dose which is received by an ordinary inhabitant in course of a year due
to the natural radioactive background (3,5 mSv / year)
- less than 1/4 of the general effective dose limit to an ordinary inhabitant
Recommended first aid at the inspiration of the gaseous tritium

legislation at the competent authority.
5. To avoid such manipulation, when a rough mechanical damage of the sights may happen.
