(such as the spokesman from the UK National Radiological Protection Board ), and in turn encouraged the public to mistrust them. [ 158 ] Throughout the European continent, in nations where abortion is legal, many requests for induced abortions, of otherwise normal pregnancies, were obtained out of fears of radiation from Chernobyl; including an excess number of abortions in Denmark in the months following the accident. [ 159 ] In Greece, following the accident many obstetricians were unable to resist requests from worried pregnant mothers over fears of radiation. Although it was determined that the effective dose to Greeks would not exceed 1 m Sv (100 m rem ), a dose much lower than that which could induce embryonic abnormalities or other non- stochastic effects, there was an observed 2500 excess of otherwise wanted pregnancies being terminated, probably out of fear in the mother of radiation risk. [ 160 ] A "slightly" above the expected number of requested induced abortions occurred in Italy. [ 161 ] [ 162 ] Other conditions According to Kenneth Mossman , a Professor of Health Physics and member of the U.S. Nuclear Regulatory Commission advisory committee, [ 163 ] the "LNT philosophy is overly conservative, and low-level radiation may be less dangerous than commonly believed". [ 164 ] Yoshihisa Matsumoto, a radiation biologist at the Tokyo Institute of Technology, cites laboratory experiments on animals to suggest there must be a threshold dose below which DNA repair mechanisms can completely repair any radiation damage.
