What is Radiation?

3The Electromagnetic SpectrumWaveform of Radiation
4Difference between ionizing andnonionizing radiationEnergy levels:Ionizing radiationhas enough energy to breakapart (ionize) material with which it comes incontact (knock off e-)Non ionizing radiationdoes not
5Types ofIonizingRadiationImportant inhealthcare:Diagnosing - X-Rays, PETScans, Nuclear MedicineTherapy - RadiationTreatment, NuclearMedicine
6Sources of Radiation ExposureNaturally occurring sources– ground, atmEnvironmental radiation– power plantsMedical procedures (patient)– x-ray, chemoOccupational sources (worker)- airports
7Penetrating electromagnetic waves – can causeinternal damageCan pass through soft tissue, but not boneOriginate in outer part of atomUsed in medical procedures (diagnostic, CT, fluro)Energy inversely proportional to wavelengthThe shorter the wave, the stronger the energyX-Ray
