Radiation Protection w/ Biology
Question | Answer |
---|---|
produces positively and negatively charged particles (ions) when passing through matter | Ionizing Radiation |
effective measures employed by radiation workers to safeguard patients, personnel, and the general public from unnecessary exposure to ionizing radiation. | Radiation Protection |
Creation of unstable atoms Production of free electrons Production of low energy xray photons Creation of reactive free radicals Creation of new biologic molecules Injury to the cell that may manifest itself | Consequences of Ionization of Human Cells |
Ionizing radiation penetrating body tissues primarily by ejecting electrons from the atom composing tissue. Limiting the Energy Deposited on tissue Reduce potential for biological effects | Biologic Effects |
Destructive radiation interaction at the atomic level results in molecular change | Cellular Damage |
Benefits have to outweigh the slight risk of inducing a radiation induced malignancy Purpose MUST be Prudent Illness and or Injury Mammography | Risks vs benefit |
The degree to which the diagnostic study accurately reveals the presence or absence of disease in the pt. | Diagnostic Efficacy |
Bone marrow does not produce sufficient new cells to replenish RBCs | Aplastic Anemia |
Depressed WBC, RBC and platelet count | Pancytopenia |
Hematological malignancies Types of cancer that affect blood, bone marrow, and lymph node | Leukemia |
