After the alpha decay of polonium-212, there is lead-208
212/84 Po --------> 208/82 Pb + 4/2 He Lead 208
an alpha particle
Thorium-230 is an alpha emitting radio-isotope.The half-life is 75 380 years, the daughter isotope is radium-226.; the energy of alpha rays is4,447 MeV.
Plutonium 238 is an alpha emitter; the decay product is uranium 234.
In alpha decay, the atomic number decreases by 2, while the atomic mass number decreases by 4.
The decay of 212Po84 goes like that:212Po84 ----- 4a2 + 208Pb82The lead isotope that forms, 208, is stable.
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
Product of radioactive decay 42He is an alpha particle
The decay product of uranium 238 by alpha disintegration (not beta or gamma) is thorium 234.
227Ac89
No. Decay is the process, radiation is the product.
Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
plutonium-239
The alpha decay of americium-241 produce neptunium-237.
An alpha particle
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
An alpha particle
No for 2 reasons:1. Wolfram Alpha is a product, not a business2. Wolfram Research, the company that produces Wolfram Alpha, is privately held.
