Tc-99 has a beta disintegration to Ru-99.
T99 is Technetion 99 has a Decay rate of 6h
Technetium-99 is produced through the decay of Molybdenum-99. Molybdenum-99 undergoes beta decay to form Technetium-99, with the emission of a beta particle (electron) and an antineutrino. This decay process is commonly utilized in nuclear medicine for imaging and diagnostic purposes.
Radium 226 has decays by Alpha emmision to produce Radon-222. Sometimes a gamma ray is emmited at the same time and lower energy alpha is emitted the product is same in both cases. Gamma emmision by itself causes no change to the atom the nucleus just ends up with a lower energy.
Technetium is not really dangerous. Since doctors will often use Technetium 99 as a radioactive tracer. It may be radioactive but its decay is slow and will produce a minute amount of gamma rays.
Technetium-99 has 56 neutrons.
This depends on a specified isotope of technetium !
In the nucleus of molybdenum, a neutron undergoes beta decay, transforming into a proton and emitting an electron and an antineutrino. This process converts the element into technetium by increasing the atomic number by one and maintaining the same mass number.
The equation for the beta decay of 165Ta is: 73165Ta --> 72165Hf + 10e + ve where the e is a positive beta particle or positron.
Technetium-99 is used as standard source for beta radiation.
The atomic mass (not molecular weight) of technetium-99 is 98,906 254 7(21).
14 7 N
Technetium-99 has not a chemical equation but an isotopic symbol. This is Tc with:- to the left, as a superscript, 99- to the left as a subscript, 43
