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

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

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

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

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

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

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
