What Is The Half Life Of Strontium 90 at Life

What Is The Half Life Of Strontium 90. (a) the decay rate of strontium 90 is (b) after 10 years, 391.74 grams of strontium 90 be left. Because of its chemical resemblance to calcium, it is assimilated in bones and teeth, where it continues ejecting electrons that cause radiation injury by damaging bone marrow, impairing…

One gram of pure 90 strontium has a radioactivity of 5.11 tbq. Of half lifes time passed (years) fraction remaining activity 0 0 1 5000 1 ½ 2500 2 ¼ 1250 3 1/8 625 4 1/16 312.5 120 3 half lifes is 120 years, so 1 half life is 120/3 = 40 years half life = Can create halide, oxide, and sulfide compounds.

The β [beta] particles radiated by 90y are of a high energy while those emitted by 90sr are of a moderate energy. Its beta radiation is not penetrating, which makes it difficult to measure when it is in the soil or a matrix. If you start with 10 grams of 90 sr and wait 28.8 years, you'll have 5 grams left of 90 sr. One gram of pure 90 strontium has a radioactivity of 5.11 tbq.
