MEN who work with radiation are no more likely than others to have offspring
with birth defects, according to a major British study of nuclear industry
workers and their families. The finding eases fears that low levels of radiation
might increase this risk.

Epidemiologists from the London School of Hygiene and Tropical Medicine and
the Leukaemia Research Fund followed the fate of 23,676 pregnancies where the
father worked in the nuclear industry. They found the fetuses of fathers exposed
to radiation had the same risk of being miscarried or born with birth defects as
those of unexposed workers.

But the results for 3585 babies whose mothers worked in the industry were
less clear. Miscarriages in early pregnancy and stillborns were slightly higher
among women exposed to radiation, but the figures are 鈥渄ifficult to interpret
because the numbers are small鈥�, says one of the study鈥檚 authors, Noreen
Maconochie. The study calls for more research. But the acting health and safety
director at British Nuclear Fuels, Roger Coates, says it may be time to end such
research, in the absence of 鈥渁ny real evidence of a health effect鈥�.
