Ion-Chamber Survey Meter |
General Meter Information
 |
The survey meter must be used to determine the background radiation levels in the room prior to operating the unit. |
|
The survey meter must also be used to monitor radiation levels while the unit is operating. |
Meter Turn-on Sequence
| 1. Turn meter on by depressing ON/OFF switch. |
| 2. Allow several minutes for the meter to stabilize. It may take up to four minutes for the instrument to stabilize. |
| 3. It is not necessary to use the Mode switch. |
| 4. The survey meter will indicate ambient background in uR/hr units. |
Note:
| If the instrument fails to operate: | |
|
Do not proceed with the irradiation procedure. |
|
Contact the Radiation Safety Office at 1-9826. |
Pre-Operational Survey of Irradiator
| 1) Determine the ambient background exposure rate in the room and record the measurement in the log book. |
| 2) Measure the exposure rate at the front of the sample chamber before operation of the irradiator. |
|
If measured exposure rate at the sample chamber exceeds 2000 uR/hr: |
|
|
Do not operate the irradiator. |
|
Vacate the room. |
