Presentation Transcript

Uses of Radiation:

Uses of Radiation Research Particle Accelerators “atom smashers” Power Generation Nuclear (fission) reactors Chain reaction of atom splitting

PowerPoint Presentation:

Tracers Used by doctors to diagnose medical problems Used by archaeologists to determine the age of artifacts & fossils Used by chemists to study reaction mechanisms

Biological Effects of Radiation:

Biological Effects of Radiation All radiation has an effect on living organisms Can penetrate cells; may disrupt function May disrupt nucleic acids (genetic material)  Cancer

Exposure to Radiation:

Exposure to Radiation Radiation is all around us Rocks, building materials, smoke alarms, cosmic rays Very small amounts that we are exposed to Penetrating ability varies depending on the type of radiation Alpha is least, Gamma is most penetrating
