LRA 216 Class notes with tests and solutions
1.Describes the different units of measurement for radiation depending on
what is being measured: The United States = Conventional units of
measurement.
Globally = System International Units of measure =
(SI) Based on units of ten and expressed by the
sievert
2.Radiation dose limits for personnel receiving 10% of the annual dose
limit or higher are set by:: National Council on Radiation Protection
(NCRP)
3.National Council on Radiation Protection (NCRP) Report No. 116 is the
basis for what?: Establishing dose limits for both patient and
occupational exposure
4.The Measurement Radiation in Air/ Exposure can be expressed by:
Conven- tional = Roentgen (R)
SI = Air KERMA/ C/kG
5.The absorbed dose in matter from any type of radiation can be
expressed by:: Conventional = Rad (Radiation Absorbed Dose)
SI = Gray (Gy/ mGy)
6.The effective/equivalent dose can be expressed by:: Conventional =
Rem (Radiation Equivalent in Man)
SI = Sievert (Sv / mSv)
7.What is Rationale behind the use of Radiation Protection:: It is to lessen
the likelihood of damage to the cells and offspring of humans exposed
to ionizing radiation.
8.The public has an annual effective dose limit that is the amount
allowed for people exposed occupationally.: 1/10th
9.Film badges, Thermoluminescent Dosimeters (TLD), Optically
Stimulated Luminescence Dosimeter (OSL), and Pocket Dosimeters are all
considered what:: Personnel dosimeters
10.The types of personnel dosimeters used in diagnostic radiology include:-
: Film badges
Thermoluminescent Dosimeters (TLD)
Optically Stimulated Luminescence Dosimeter

, (OSL) Pocket Dosimeters
11.This type of dosimeter is commonly worn as finger rings by nuclear
medicine personnel to measure occupational exposure to their hands
from handling radioisotopes: Thermoluminescent Dosimeters (TLD)
12. This type of dosimeter is capable of measuring different energy
ranges and is especially desirable when monitoring pregnant workers.:
Optically Stimulat- ed Luminescence Dosimeter (OSL)
13.This type of dosimeter provides instantaneous readings but must be
recal- ibrated daily and resembles a fountain pen.: Pocket Dosimeters
