Why are technetium and promethium radioactive?Radioactive:Radioactivity is a process of emission of radiation in form of particles or energy. It emits via radioactive decay. There are three processes of radioactive decay, which are gamma, alpha, and beta. Radioactivity occurs in an unstable ...
How is deuterium produced? Can deuterium be used as fuel? Why is californium radioactive? Why are technetium and promethium radioactive? Why were the proton and electron discovered before the neutron? How does a deuterium lamp work? Why is there a strong nuclear force between protons?
Gamma radiation isoften used to kill living organisms, in a process called irradiation. ... The most common gamma emitter used in medical applications is the nuclear isomer technetium-99m which emits gamma rays in the same energy range as diagnostic X-rays. Why is a beta emitter used rather...
it was artificially created — with technology.And people thought that synthesizing this element, making it artificially, was the only way to get it.We still hadn’t found it occurring in nature.Now, element 43, whether you call it masurium or technetium, is radioactive.Why does that matter...
