Chapter 4d Flashcards
Absorbed dose
Radiation energy absorbed per kilogram of tissue
Cancer v cell
Harmful tumour caused by uncontrolled cell division v microscopic structure that makes up tissue
Effective v equivalent dose
Measure of bio impact of radiation v measure of organ specific Impact of radiation
Ionising impact
Ability of ionising to cause damage
Medical radioisotope
Radioisotope used in diagnosis or treatment of Illness
Radiation weight factor v tissue
Relative bio effect of radiation type v group of speciallised cells
Tissue weighting factor
Relative danger of radiation absorption in a particular tissue
Higher effective dose v higher equivalent dose
High risk of illness in particular tissue v overall higher risk of illness somewhere in the body
Weight factor of radiation
Alpha 2
Beta 1
Gamma 1
Tissue weighting factor
Brain .010
Liver .040
Lungs .12
Stomach .12
Higher is higher sensitivity to develop radiation poisoning
Radiation effect on human body
For absorbed below 1 gy unlikely to experience short term effect for 1-3 immediate health risk like nausea and burn over 10 death is likely from 3.5 to 5 around 50 percent of people will survive
General medical relation
Radiation can cause cancer as well as treat cancer internally and externally through damage of malignant (harmful) cells
How radioisotopes use in medical therapy and Ability of radiation types to penetrate skin and ionising impact as well as ability of different radiation forms to damage cells
