Block 4 Unit 1 C exam with correct answers
Why do we use the RADeCO to monitor the air? - correct
answers✔✔We must have equipment that we can use in a
passive manner that samples large amounts of air
How does the RADeCO pull air through the filter mounted on
the right side of the unit? - correct answers✔✔The RADeCO has
a two stage turbine fan that creates a negative pressure
What is the filter in the RADeCO made of? - correct
answers✔✔It is a 4 inch diameter high efficiency glass-fiber
filter
What indicates the RADeCO airflow? - correct answers✔✔The
air passes by a rotometer
What can be done to maintain high enough air flow velocities to
most effectively capture concentrated radioactive particulates
on the filter? - correct answers✔✔The airflow can be adjusted
, What happens once the filter has been exposed for a
designated operating time or airflow volume? - correct
answers✔✔The filter is monitored in place or removed and
monitored with a radiation survey meter
What must the RADeCO not come in contact with? - correct
answers✔✔Care must taken to prevent it from coming in
contact with foam, liquid (including water), and other foreign
aubstances
The RADeCO is not intrinsically safe so where should it not be
operated in? - correct answers✔✔In an explosive atmosphere
How long should the RADeCO warm up before use? - correct
answers✔✔It should warm up for 5 minutes
Why does the RADeCO need to warm up for 5 minutes? -
correct answers✔✔Because there will be an increase in airflow
while the system is warming up during the first five minutes
What must be done in order not to damage the digital
calibrator? - correct answers✔✔Turn the RADeCO's FLOW
