A banana contains naturally occurring radioactive material in the form of potassium-40.. Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana.
The idea of ray cats has gained popular-culture notoriety, including inspiring a song that is meant to be optimally catchy so as to persist for 10,000 years. A 2019 report by the Nuclear Energy Agency concluded that Bastide and Fabbri succeeded at their real goal, raising awareness about the difficulties of dealing with radioactive waste. [2]
The device contains trace amounts of the radioactive isotope Germanium-68, which is used as a radiation source for one of the cancer center's CAT scan machines.
The banana equivalent dose is the dose of ionizing radiation to which a person is exposed by eating one banana. Bananas contain potassium . Natural potassium consists of 0.0117% of the radioactive isotope 40 K (potassium-40) and has a specific activity of 30,346 becquerels per kilogram, or about 30 becquerels per gram.
The shipment was a piece of medical equipment called a pin source, which contains a radioactive component commonly used to calibrate PET scanners. The pin source has since been recovered.
1 Bq = 1 s −1. A special name was introduced for the reciprocal second (s −1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes.For example, 1 μs −1 would mean 10 6 disintegrations per second: (10 −6 s) −1 = 10 6 s −1, [4] whereas 1 μBq would mean 1 disintegration per 1 million seconds.
