The statement of the Chairman of Indian DAE at IAEA has some interesting pointshttp://dae.nic.in/writereaddata/gc2014_0.pdf
On page 4 of the document, successful separation of actinides from fission products has been claimed. This could provide a more economical, non-proliferating means of providing fissile feed to thorium powered or fast reactors.
A quotation from page 7 is also of interest.
The human population living in Kerala coast in South west India is continuously exposed to natural background radiation emanating from the monazite-bearing sand, with the dose varying up to a high of 45 mGy per year in the High Level Natural
Radiation Areas (HLNRA), compared to less than 1.5 mGy per year in some other places in the same area (that is similar to Normal Level Natural Radiation Areas, NLNRA). As a part of on-going research of screening newborns in these areas in India, the studies have now exceeded 160,000 newborns; these studies did not reveal any statistically significant difference in the frequency of any type of malformations and stillbirth after adjusting for the confounding factors such as maternal age at birth, consanguinity, ethnicity, etc., and frequency of Down syndrome. Adaptive response studies are in progress using end points such as chromosome aberration, micronuclei and gene expression pattern.
This study could form the basis of a more rational view on radiation.
