Across
- 2. Illness s/s include fever, fatigue, loss of appetite, lethargy, anemia, leukopenia, hemorrhage, infection, electrolyte imbalances, emaciation.
- 3. stochastic effects includes cancer, genetic effects
- 6. risk model predicts that a specific number of cancers will occur as a result of exposure.
- 7. 50/30 signifies the whole-body dose of radiation that can be lethal to 50% of exposed population within 30 days
- 8. of ARS Hematopoietic syndrome, gastrointestinal syndrome, cerebrovascular syndrome.
- 10. effects biologic effects of ionizing radiation on future generations due to irradiation of germ cells in previous generations.
- 11. effects long term results of radiation exposure
- 12. Syndrome- 50+ Gray, death occurs. Damaged blood vessels and permeable capillaries permit fluid to leak into the brain, causing increased ICP.
- 14. deterministic Somatic Effects-Includes cataract formation, fibrosis, organ atrophy, loss of parenchymal cells, reduced fertility, sterility
- 15. stages Prodromal, latent period, manifest illness, death or recovery.
- 17. effects damage to non-reproductive cells, may be early or late effects. Self.
- 18. Period may last 5 days- 4 weeks. No symptoms are visualized. “False calm”
- 20. Syndrome appears at a threshold of 6-10 Gy and peaks after a dose of 10Gy. Death occurs in 3-5 days due to catastrophic damage to the epithelial cells that line the GI tract, fluid loss, or dehydration. Can be prolonged with medical support to 3-10 days.
- 21. the production or origin of cancer.
Down
- 1. aka non-random, threshold
- 4. Radiation Syndrome(ARS, radiation sickness) early somatic tissue reactions, occurring in humans soon after whole body reception of large doses of ionizing radiation delivered over a short period
- 5. curve (DR curve) goal is to establish relationships between radiation and dose response.
- 7. threshold (LT)- biologic response does not occur below this dose
- 9. Syndrome aka bone marrow syndrome- occurs when people receive whole-body doses of ionizing radiation from 1-10 Gray. Causes the number of RBC, WBC, and platelets in circulating blood to decrease. Body becomes more susceptible to infection and to hemorrhage. Death occurs in 6-8 weeks in some who receive a whole body dose of 2 Gray, larger doses will cause death sooner. If a sublethal dose of 1-2 Gray pt may recover in 3-6 weeks.
- 13. risk model predicts the number of excess cancers will increase as the natural incidences increases with advancing age. Predicts a percentage increase rather than a specific number.
- 16. aka random, probabilistic, non-deterministic, non-threshold
- 17. Threshold-High dose response in radiation therapy
- 18. non threshold (LNT) response to radiation is directly proportional to the dose of radiation
- 19. A few hours after irradiation, severe N/V/D persists 24 hrs
- 22. effects- occur soon after humans receive large doses of irradiation
