As far as health effects are concerned the safety model of the European Committee on Radiation Risk, ECRR 2010 is available at
The recommendations include a maximum annual dose of 0.1 mSv to a member of the public involving radiation exposure, both internal and external. This is a cumulative dose for a 65 year life is 6.5 mSv.
The dose to a nuclear worker is recommendation of 2 mSv per annum. The life time cumulative dose is thus a maximum of 0.1 Sv.
Now look at the dose adopted at the Kudankulam Nuclear Power Plant and recommended by The International Commission on Radiological Protection (ICRP): Annual dose to a
member of the public: 1 mSv. The 65 year cumulative dose is 65 mSv. Annual dose to a nuclear worker 20 mSv, with a cumulative lifetime dose of 1 Sv.Ref: http://www.thehindu.com/multimedia/archive/00841/Expert_Group_report_841167a.pdf
The ECRR health effects of exposure to low dose radiation is based on a radiation risk model whose implications are set out in the ECRR 2010 recommendations on exposure to ionising radiation:
The ECRR 2010 recommendations are thus an order of magnitude lower than that recommended by the ICRP.
This alone requires a public deliberation of profound dimensions! The ECRR is of the opinion that ICRP recommendations are not scientific for internal radioactive contamination(See the pdf reference cited above).
How can nuclear be an option, if it is to be safe. The Kudankulam nuclear plant's health effects are totally
unacceptable.
