Naturally occurring strontium is nonradioactive and nontoxic at levels normally found in the environment, but 90 Sr is a radiation hazard. [4] 90 Sr undergoes β − decay with a half-life of 28.79 years and a decay energy of 0.546 MeV distributed to an electron, an antineutrino, and the yttrium isotope 90 Y, which in turn undergoes β − decay with a half-life of 64 hours and a decay energy ...

Strontium 90: Police Academy is the only album by Strontium 90, released by Mike Howlett in 1997. This album consists of live tracks recorded at Gong's reunion concert in Paris on 28 May 1977, five studio tracks recorded in London just before the concert, and Sting's solo demo of "Every Little Thing She Does Is Magic".
Strontium-90 has a shorter half-life, produces less power, and requires more shielding than plutonium-238, but is cheaper as it is a fission product and is present in a high concentration in nuclear waste and can be relatively easily chemically extracted. Strontium-90 based RTGs have been used to power remote lighthouses. [1]
The generator contains the strontium-90 radioisotope, with a heating power of 250W and 1,480 TBq of radioactivity – equivalent to some 280 grams (9.9 oz) of Sr-90. [4] Mass-scale production of RTGs in the Soviet Union was the responsibility of a plant called Baltiyets, in Narva , Estonia .

The strontium unit is a unit used to measure the amount of radioactivity from strontium-90, a radionuclide found in nuclear fallout, in a subject's body. Since the human body absorbs strontium as if it were calcium , incorporating it into the skeleton , its presence is very common.
