The break down of the atomic nucleus. 16.2 Alpha, Beta, and da Gamma RaysAlpha: absolute (+2), Large mass Beta: Electrons ejected from nucleus and confine a single negative charge.Gamma: High frequence electromagnetic irradiation . It is pure qualification, made of protons. 16.3 Environmental Radiation spark plead source of natural radiation is Radon-222. 1/5 comes from in the main medical procedures. 10,000 tons of radioactive waste apiece year, worldwide. A. Units A. measured in Rads (radiation absorbed process) 1 rad = .01 watt second absorbed per kilogram of tissue The type radiation not the dose size determines the endangerment. Radiation dosage of potential danger rem (roentgen equal man). B. Doses B. Doses: Lethal doses of radiation b egin at 500 rems. Exposeure in mrem 1/1000th of a rem. cheek cells are not renewable. Mutated cells can deal to cancer. C. Tracers: C. Tracers: Radioactive isotopes use To trace pathways.

16.5 Radioactive Half-lifeThe rate of decay for a radioactive isotope is Measured in terms of a characteristic time, The half-lifeHalf-life not affected by outside conditions. 16.7 Radiometric DatingKnown as carbon dating Carbon-14 has 8 neutrons radioactive: Carbon-12 has 6 neutrons non-radioactive 16.8 atomic FissionElongating electrical forces to have the best strong nuclear forces causing the nucleus to split.
