Medicine Technology Guide, Practice Questions
& Review Q&A
Caution Radiation Area - More than 5 rem (.05 mSv) in 1 hr at 30 cm from source
Caution High Radiation Area - More than 100 rem (1 mSv) in 1 hr at 30 cm from source
Usually where Radiation therapy is performed.
Grave Danger Very High Radiation Area. - 500 Rad in 1 hr
Unrestricted Area - Person could not be exposed to in excess to 2 mr/hr
Restricted area - Controlled access area for the protection of individuals from exposure
to radiation.
Posting exemptions - Licensee is not required to post a room containing RAM for 8 hrs
or less. Materials must be constantly attended.
Surveys of individual doses, bioassay' and release of radioactive effluents - Licensee
shal maintain these records until termination of the license.
Hazmat - Any substance or material that is capable of posing an unreasonable risk to
health, safety and property when transported in commerce.
Hazmat training - Within 90 days of employment and every 3 years.
, Transportation index (TI) - Maximum radiation level in Millirem hr at 1 meter. Must be
rounded up the next tenth.
UN2908 - Empty class 7.
'White 1 package - Surface <0.5 mr/hr.
1 meter = bkg
Yellow II - Surface < 50 mr/hr
1 meter = 1 mr/hr
Yellow III - Surface < 200
1 meter = 10 mr/hr
Type A package - Adequate for normal transport.
1,2,3
Type B - Used for large quantities of radioactive material
Caution radioactive materials - Where radiation is used or stored.
Usually entrance of labs.
UN 2910 - Limited quantity of radioactive material
Less than 0.5 mr/ hr
UN2915 - Used for: white 1, yellow,2 and yellow 3
Yellow III requirement - Driver must have hazmat cdl license and vehicle must be
placarded
Wipe test - Legal limit = 6,600dpm/300cm^2 or 22dpm/1cm^2
Returned containers - -no removable contamination
-surface reading <0.5 mr/hr
Syringes with blood must be marked as biohazard
To convert mci to GBq - 1 mci = .037GBq
27 mci = 1 GBq
