Banana Officially Tired of Being Used as Unit of Radiation Measurement

The International Banana Growers Association held a press conference Monday demanding that the health physics community cease using the 'banana equivalent dose' as a unit of radiation measurement, calling the practice 'reductive, stigmatizing, and devastating to banana sales in communities near nuclear facilities.' 'Every time there's a radiation incident, some physicist goes on television and says it's equivalent to eating 14 bananas,' said association president Carmen Potassium. 'Do you know what that does to banana sales? We lost 12 percent of our market in the Fukushima prefecture. Twelve percent. Because of a metaphor.' The banana equivalent dose, approximately 0.1 microsieverts, has been used for decades by health physicists to contextualize radiation exposure for the general public. It is based on the potassium-40 naturally present in bananas, which emits beta particles and gamma rays during radioactive decay. 'It's a useful pedagogical tool,' said Dr. Franklin Sievert of the Health Physics Society. 'When we tell people a CT scan is equivalent to eating 70,000 bananas, they immediately grasp the scale. The banana is performing an invaluable service to public science communication.' 'The banana did not consent to this service,' Potassium fired back. 'The banana is a food. It is not a dosimeter. It did not ask to be the poster fruit for ionizing radiation.' The association has proposed alternative comparisons, including 'the Brazil nut equivalent dose' (Brazil nuts contain significantly more radium-228 than bananas) and 'the granite countertop equivalent dose,' neither of which have gained traction because, as Dr. Sievert noted, 'nobody wants to eat 70,000 Brazil nuts.' The banana's potassium-40 was unavailable for comment, as it was busy decaying at its characteristic half-life of 1.25 billion years.
