Natural Radiation and Radioactivity

1.2.6.2
Natural Background: Populations
 

Professor Luckey reports further on the effect of radiation on reproduction (1991) that

"Fertility is more than the flip side of sterility; it includes embryo viability and quantitative as well as qualitative factors. The poorly fed coastal population in Kerala receives 4-8 times more background radiation than the average for other areas. The people of Kerala have a higher fertility rate with the fewest neonatal deaths than any other state of India.

"The high terrestrial radiation, 9 mGy/year, in Espirito Santo, Brazil, did not affect the fertility or fecundity of 8000 couples. (Freire-Maya 1978)"

"When Chinese women over 35 years old were chronically exposed to three times more background radiation than the control group, they had more children than the control women, p<0.05. (Wei et al. 1986) There was no difference in fertility of younger women between the two groups."
