Radium 226 would be the great great granddaughter of Uranium 238.
Uranium 238 decays to Thorium 234 with a half-life of 4.5 billion years.
Thorium 234 decays to Protactinium 234 with a half-life of 24 days. (child)
Protactinium 234 decays to Uranium 234 with a half-life of 1.2 minutes. (granddaughter)
Uranium 234 decays to Thorium 230 with a half-life of 240,000 years. (great granddaughter)
Thorium 230 decays to Radium 226 with a half-life of 75,000 years. Radium 226 has a half-life of 1600 years.
Subsequent decay products are:
- Radon 222 (half-life = 38 days)
- Polonium 218 (half-life = 3.1 minutes)
- Lead 214 (half-life = 27 minutes)
- Bismuth 214 (half-life = 20 minutes)
- Polonium 214 (half-life = 160 microseconds)
- Lead 210 (half-life = 22 years)
- Bismuth 210 (half-life = 5 days)
- Polonium 210 (half-life = 138 days)
- Lead 206 (stable - does not decay further)

Is uranium nuclear fuel?
Yes, U233, U235, and U238 are all used as nuclear fuels.
Who is ingrid pitts granddaughter?
Sofia Blake is her very much loved granddaughter.
Which has the greater number of protons between U-235 or U238?
All isotopes of uranium have the same number of protons, 92. A nuclide with a number of protons other than that is not uranium.
What does the breakdown of uranium release?
U238 releases a small part called alpha radiation and a large part known as the decay product.
How many neutrons are in Element 92?
Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons
