The half life of polonium-214 is 164,3(20) microseconds.
Po-214 has a half life of approx 160 microseconds.
Polonium-218 decay to lead-214.
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
Bismuth-214
Polonium-218-------------alpha---------------Lead-214
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
The equation for the alpha decay of 210Po is: 84210Po --> 82206Pb + 24He representing the alpha particle as a helium nucleus. 206Pb, the daughter atom, is stable.
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
210 4 214 84 PO -------> 2 alpha + 86 RN
All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
Polonium-210 decay to lead-206.
210 4 214 84 PO -------> 2 alpha + 86 RN
Polonium isotopes are decay products of thorium or uranium.
