How do you find the half-life of bismuth?

The scientists registered 128 alpha-particle events over 5 days and found an unexpected line in the spectrum at 3.14 MeV – now attributed to bismuth-209 decay. The half-life was calculated to be (1.9 +/- 0.2 ) x 1019 years, which is in good agreement with the theoretical prediction of 4.6 x 1019 years.

How many neutrons are in bismuth-210?

Bismuth-210 is composed of 83 protons, 127 neutrons, an 83 electrons.

What type of decay does polonium-210 undergo?

alpha particles
Po-210 decays to stable lead-206 by emitting alpha particles, accompanied by very low intensity gamma rays. The majority of the time Po-210 decays by emission of alpha particles only, not by emission of an alpha particle and a gamma ray. Only about one in a 100,000 decays results in the emission of a gamma ray.

How do you find the half-life?

The time taken for half of the original population of radioactive atoms to decay is called the half-life. This relationship between half-life, the time period, t1/2, and the decay constant λ is given by t12=0.693λ t 1 2 = 0.693 λ .
