How Real is the Risk from Technologically Enhanced Natural Radiationplant and a larger fertilizer industry have been investigated as a source of natural radiation with possible synergistic effects from chemical contaminants..During the investigations indications of the existence of threshold levels were obtained. In this case a de minimis level could be based on the observability of health effects.

Estimating Risks of Known and Unknown Carcinogensdata, the calculated risk is very uncertain. Many people reject the idea of calculating risks and suggest that only a priority order is possible. But a risk still exists, however uncertain its calculation. A priority order based on uncertainty of information is different from one based on risk; yet
