[...] Epidemiological studies, backed by animal experiments, have established beyond doubt that exposure to radiation levels above 100 millisieverts increases the risk of cancer in a predictable, dose-dependent way. But the risk to health at lower exposure levels is harder to pin down. In Germany, for example, the dose limit for occupational exposure is 20 millisieverts per year. But even when this limit is respected, there are more than 70,000 reports of suspected health damage among exposed workers each year, more than double the number in 1960. Some epidemiological studies suggest that low doses of radiation — as few as 10 millisieverts in children — may increase cancer risk in susceptible individuals, and may be associated with other conditions, such as heart disease and stroke. People living close to Fukushima are anticipated to receive around 10 millisieverts of accumulated radiation exposure each over the next decade. [...]
