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.
It was not possible in 1984 to genetically engineer cats in the manner proposed. [10] In 2015, Bricobio, a Montreal-based biology lab, created the Ray Cat Solution movement, [22] which seeks to engineer cats that can change color in response to radiation or other stimuli and runs a website promoting the idea of ray cats.

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 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 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.

AN OIL RIG CAT: At the ANode, Oxidation Involves Loss of electrons. Reduction Involves Gaining electrons at the CAThode. [26] LOAN - Left Anode Oxidation Negative. In written representation of galvanic cell, anode is written on the left. It is the electrode where oxidation takes place. It is the negative electrode. Obviously, the opposite ...
