Document Summary
X-rays discovered by wc rontgen in 1895, noble price 1901. Ionizing radiation charged electron ejected from outer orbit, energy from the release of a photon, different electron takes place of old one. Electromagnetic spectrum different frequency and wave lengths. Ionizing can change shape of cells in body. Developing aplastic anemia (create red blood cells) X-ray tube cathode, anode (ionization produce photons) Depending how thick or dense, photons may move through or not creates image when hits image receptor. As low as reasonably achievable alara principle. No safe dose , keep dose to a minimum, don"t do it if not required. Safety code 35 federal legislation: limits for workers, students, and public. Duty of radiographer to protect self, patients, and public. Physical barriers specific rooms, lead in walls (lead-line barriers) Lab safety tld (thermoluminescent dosimeter), everyone gets their own to wear in lab attached to sin number.
