Thallium has several isotopes, with thallium-204 being stable, while thallium-201, which is commonly referenced in decay discussions, has a half-life of about 73 hours. Other isotopes, like thallium-202 and thallium-203, have half-lives of 12.3 days and 46.5 hours, respectively. The decay time varies depending on the specific isotope in question.
This isotope is lead-206.
Thallium is not a product of β-ray (beta particle) emission itself; rather, it can be formed as a result of the decay of certain heavier elements. In beta decay, a neutron in the nucleus transforms into a proton, emitting a beta particle (electron or positron) and resulting in a new element with a higher atomic number. For example, thallium-204 can be produced from the decay of lead-204 through beta decay.
Thallium 203 in my reference is stable. Thallium has many isotopes from Tl184 (11 sec half life) to Tl210 (1.30 min).
In alpha decay, the nucleus emits an alpha particle (helium nucleus) consisting of 2 protons and 2 neutrons. Thallium-230 undergoes alpha decay to produce an alpha particle (helium-4 nucleus) and become lead-226. The balanced nuclear equation for this process is: ([^{230}{81}Tl \rightarrow ^{4}{2}He + ^{226}_{82}Pb]).
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.

When bismuth-212 undergoes alpha decay, it becomes thallium-208.
Thallium 203 in my reference is stable. Thallium has many isotopes from Tl184 (11 sec half life) to Tl210 (1.30 min).
The neptunium decay series is finished with the stable isotope thallium-205.
Radium itself continues to decay into radon, bismuth, polonium, lead, or thallium.
In alpha decay, the nucleus emits an alpha particle (helium nucleus) consisting of 2 protons and 2 neutrons.

Sheet metal can take hundreds to thousands of years to decay, depending on factors such as the environment and the type of metal.
The product of beta decay of bismuth-209 is thallium-209. During beta decay, a neutron in the bismuth nucleus is converted into a proton, resulting in the emission of a beta particle (electron) and an antineutrino.
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
