Moving from under the lamppost: can epidemiologists and radiobiologists work together?

Understanding and evaluating the health effects of prolonged exposure to lo w radiation doses, as opposed to shorter exposure to higher doses, has stil l a long way to go. Answers to these questions cannot be provided by epidem iological studies alone, and so the input of radio-biologists to help focus the work of epidemiologists will become increasingly important in the futu re. This paper discusses the current research status in this field and emph asizes the importance of interaction between radiation epidemiologists and radiation biologists.
