Discuss what is meant by ALARA - ANS -ALARA Stands for as low as reasonably achievable
, -it is aimed at reducing radiation exposure and individuals who work routinely with radiation
Define the three units of measurement for radiation exposure - ANS Roentgen (R)
radiation absorbed dose (RAD)
radiation equivalent man (REM)
Defined the 3 units of measure for radiation exposure - ANS -Roentgen is a term applied to
x-rays and gamma rays it is the amount of radiation it takes to produce one electrostatic charge
in 1 cc of dry air at standard temperature and pressure
K
-RAD Encompasses all types of radiation not just x-rays and gamma rays
-REM Is the unit of measure apply to radiation exposure in humans
C
Explain how personal monitoring devices should be worn - ANS -All film badges should be
worn in the area of the body at risk of greatest radiation exposure usually the chest or collar
LO
area
- individuals who wear devices on fingers such as nuclear med techs should not have the device
facing away from the palm
-finger badges should be worn so they are facing the radioactive material while injection is being
performed
YC
What type of event is reportable to the NRC - ANS -I 131 to the wrong patient
-administer doses that exceed 20% of the total prescribe dose
- single therapeutic dose
that varies by more than 20% from the written directive or a weekly therapeutic dose to varies
D
by more than 30% from the written directive
Discussed the methods for determining if an area is contaminated - ANS -An area survey
U
should be performed daily to check for radio active contamination in areas were
radiopharmaceuticals are assayed, prepared, and administered
-an area survey should be performed on a weekly basis in all areas where radiopharmaceuticals
ST
are stored and where radioactive waste is placed for decay
-A wipe test should be performed on a weekly basis in all areas were radioactive materials are
prepared administered or stored
Explain the proper methods for disposal of radioactive waste - ANS Radioactive patient urine
and feces can be legally disposed of by releasing them into the sewer
-Store waist until radiation levels decayed background level then dispose of the waste in the
regular trash or biohazard trash
-waste can be transferred to an authorized recipients for disposal. when this method is selected
the waste must be in proper container with the proper shipping labels in order to transport it
legally
