Strontium-90 - Wikipedia
The radioactive decay of strontium-90 generates a significant amount of heat, 0.95 W/g in the form of pure strontium metal or approximately 0.460 W/g as strontium titanate [22] and is cheaper than the alternative 238 Pu.
Strontium-90 - isotopic data and properties - ChemLin
Strontium-90 decays in a β--decay with the release of an electron to yttrium-90 (half-life 64 hours) and further to the stable zirconium-90 (emission of another electron and an antineutrino). 90 Sr has a specific activity of 5.21 TBq/g.

As 90 Sr decays, it forms 90 Y or Yttrium-90 which has a half life of 64 hours. The 90 Y decay results into a stable substance called Zirconium (Zr). The β [Beta] particles radiated by 90 Y are of a high energy while those emitted by 90 Sr are of a moderate energy.
