LRA 215 CHAPTER 1 REVIEW
1.Law of Bergonie and Tribondeau: states that ionizing radiation is more
effective against cells which are highly mitotic, immature and have a
long dividing future
2.epilation: hair loss
3.direct effect: a result of ionization and excitation, an interaction that
happens DIRECTLY on a critical biologic macromolecule
4.erythema: redness of the skin
5.fractionation: a treatment radiation dose is broken down into multiple
exposures over several weeks to minimize side effects
6.indirect effect: a cell interaction that occurs when the initial ionizing
incident takes place on a distant noncritical molecule, which then
transfers the ionization of energy to another molecule
7.radiobiology: division of biology concerned with effects of ionizing
radiation on living things
8.mutagenesis: the causing of genetic mutation by radiation
9.oxygen effect: increased production of free radicals when ionization
radiation is delivered in the presence of oxygen
10.protraction: the time during which a course of radiation is given
11.RAD: Radiation Absorbed Dose, Gray (patient dose)
12.radioactivity: the effects that our cells undergo and the probability of
damage or recovery when irradiated
13.REM: Radiation Equivalent Man, Sievert (occupational dose)
14.reproductive failure: cell that is unable to continue repeated
divisions after being irradiated
15.Roentgen: radiation quantity, Coulomb/kilogram
16.Curie: radioactivity, Bequerel (x-ray quantity)
17.Whole body exposure limit: 5 rem (50 mSv)
18.lens of eye exposure limit: 15 rem (150 mSv)
19.Skin and extremities exposure limit: 50 rem (500 mSv)
20.Whole body cumulative (lifetime) exposure limit: age x 1 rem (age x 10
mSv)
21.fetus exposure limit (10 month): .5 rem (5 mSv)
22.fetus exposure limit (one month): .05 rem (.5 mSv)
23.Student exposure limit < 18 years: .1 rem (1 mSv)
24.which researcher discovered mutations related to exposure to
ionization radiation?: Muller
25.Which of the following should be considered most radiosensitive ?: fetus
26. Which researcher died due to the cumulative effects of radiation?:
