Alice Stewart was born in 1906 and had a distinguished early career as a clinical physician, becoming in 1946 the youngest woman ever to be elected a Fellow of the Royal College of Physicians. This was also the year in which she turned to Social Medicine, joining the Unit of that named in Oxford. In 1955 she and her colleagues noticed the rapid increase in leukaemia among children, which seemed likely to have environmental causes, and the idea for what became the Oxford Childhood Cancer Survey, or just Oxford Survey, was born.
One of the key early findings of this survey (1958) was that children who died of
leukaemia or cancer had been X-
Meanwhile, Stewart had become involved in a study of the nuclear industry at Hanford,
USA, which found that for a large group of workers there was evidence of a cancer
risk comparable to that of pre-
Stewart's findings, again flying in the face of all received nuclear wisdom, provoked
a further storm of controversy, but when these findings were in turn confirmed by
more analysis and were supplemented by other findings indicating disturbing radiation
effects, Stewart turned her attention to the A-
Most recently Stewart has published results that show that over 50 per cent of cancer
deaths before 10 years of age are probably caused by background radiation or pregnancy

Stewart's commitment to work that is deeply unpopular with the nuclear establishment has undoubtedly cost her academic, preferment and research funds (the initial results from the Hanford study brought about its early termination). As a Senior Research Fellow at the University of Birmingham, which she joined in 1974, she still works out of tiny offices in a team of only three. In 1996, Alice Stewart celebrated her 90th birthday shortly after being made an honorary Professor by the University.
"We have already doubled the level of background radiation today. What is the effect on human genes? That is the really important question: it won't show up for two or three more generations."
