1. Radioactive Baby Teeth
Sophie B, Moshup, Amanda, Ben, Michael
F Block

2. Strontium-90 Structure like Calcium Emits Beta particles
Decays to Yttrium (also a Beta emitting substance)
Half life: 29 years

3. Dangers of Strontium
Internal exposure causes bone cancer, cancer of the soft tissue and leukemia.

4. Tooth Fairy Project Government no longer measures radioactivity
Baby teeth sent in are measured for
Sr-90 levels

5. Chernobyl Effect
Nuclear plant explosion caused radio active material to be spread around the world
Tooth Fairy Project detects where it effected in the 1960’s

6. Radiation of Sr-90
No one is safe from Sr-90 radiation, it’s impossible to avoid
Unlikely to be effected unless within 100 miles of nuclear reactors

7. Fallout- aftermath of radiation hazard from a nuclear explosion
Nuclear Arms Race- Competition of nuclear warfare between the U.S. and the U.S.S.R.
Atomic Bomb Test- experiments to determine effectiveness of nuclear weapons
1pCi/grCa- One pico curie per gram of calcium
