Question 1
True
False
A major goal of radiation protection at Clarkson University is to keep radiation doses as low as reasonably achievable. Therefore, experiments should be carefully planned to minimize the level of exposure.
 
Question 2
True
False
The biological effects of a defined amount of radiation are more severe if the exposure is acute rather than chronic (one large dose versus smaller doses spread over time).
 
Question 3
True
False
A whole body dose of radiation causes more damage than an equivalent dose localized to one site (such as in medical therapy).
 
Question 4
True
False
Your exposure to radiation can never be zero because background radiation is always present. Total US average dose equivalent is approximately 360 mrem/year.
 
Question 5
True
False
There are occupational limits for radiation exposure that apply to scientists at Clarkson. The maximum of exposure for a scientist who works with radioactive materials is 5 rem per year TEDE (total effective dose equivalent).
 
Question 6
True
False
Since radiation is potentially more harmful to a fetus, the dose limit for pregnant women is 10% of the occupational limit, or 500 mrem per year (total effective dose equivalent).
 
Question 7
True
False
Regarding potential exposure to ionizing radiation, if you double your distance from the source of radiation, your exposure rate drops by factor of 4.
 
Question 8
True
False
Regarding potential exposure to ionizing radiation, it does not help to minimize the time that you are in contact with a radioactive source.  This is because once you become exposed, it is unlikely that you can absorb any additional radiation.
 
Question 9
True
False
It is permissible to store personal food items in refrigerators or freezers used for radioactive material, but only if they are wrapped carefully with plastic or stored in a covered container.
 
Question 10
True
False
If you have a concern or question regarding radioactive material on campus, you should call the radiation safety officer, Elayna Mellas, or the campus safety officer, Alan Rossner.
