A good way to keep your dose ALARA is to:
For a sealed source which emits beta particles, the following shielding is the best choice:
The dosimeter should be worn:
True or false: In every laboratory using radioactive sources, there should be clearly displayed a list of people, including their phone numbers, who are to be called in case of a NON life-threatening emergency.
As a researcher, you want to move a Tier I source from one building on campus to another building. What arrangements must you make?
How long is the suggested use period for a Tier II sealed source?
What level of leakage from a source will require a source to be removed from use?
True or false: Individuals working with Tier I sealed sources require both a film badge dosimeter and frequent bioassays.
The approximate rate of exposure from a sealed source emitting gamma radiation:
True or false: There is no chance of any external exposure from a Tier II source
True or false: An individual sealed source may emit more than one type of radiation.
True or false: All sealed sources, Tier I and Tier II, must be signed out when they are removed from storage for use.
Exposure is measured in units of:
A leak test of a sealed source involves:

All personnel using radiation-producing machines and/or radioactive materials at CU must complete refresher training:
True or False: The safe use of radioactive materials is best accomplished when the end user and radiation safety personnel act in cooperation
IMPORTANT! If you have worked with radiation at any institution other than the University of Colorado (Boulder, Denver, or Colorado Springs campuses only) since beginning your work here, it is your responsibility to notify Health Physics so that your lifetime dose can be tracked. Please answer the questions below before submitting your quiz.
Please list the names and addresses of any institutions where you’ve worked with radiation since beginning your work here. Please include Radiation Safety contacts and the type(s) of radiation you used.
