Limits on annual equivalent doses

Exposure

Limits on effective dose

20 mSv per year averaged over defined 5 years (max 50 mSv over one year)

The lens of the eye: 150 mSv The skin: 500 mSv The hands and feet: 500 mSv

Occupational exposure

Member of the general public • A dose of 0.5 Gy (new threshold) could readily be exceeded on the basis of the current equivalent dose limit for the lens of the eye of 150 mSv per year. • ICRP 2011-2012 recommend a dose limit to the lens of the eye of 2 v per year averaged over defined 5 years (max 50 mSv over one year) for Occupational exposure. • No new limit has been recommended for public exposur s to the lens of the eye ( 1 mSv/year was judged adequately protecti e). 1 mSv in a year (special circum 5 mSv over one yr, provided an average of 1mSv/yr for 5 consecutive yrs) The lens of the eye: 15 mSv The skin: 50 mSv Special situations Emergency situations a) effective dose limit: 500 mSv equivalent dose to the skin:5 Sv Dose limit to unborn child 1 mSv for the period to birth

a) No limits are applicable in case of life saving activities.
