Fear of radiation is more dangerous than radiation itself.

Psychologically, research has found that we worry excessively about risks that we can’t detect with our own senses, risks associated with catastrophic harm or cancer, risks that are human-made rather than natural, and risks that evoke fearful memories, such as those evoked by the very mention of Chernobyl or Three Mile Island. Our fear of radiation is deep, but we should really be afraid of fear instead.
