WARNING
Risk of injury
‣
In the case of source containers with a pneumatic actuator, the switch must be secured and
padlocked in the "OFF" position before the wipe test. In the case of manually operated source
containers, the wipe test can be performed irrespective of the switch position
1. Take a swab sample at the following points at least:
FQG61/FQG62; order code 020, option A, B, C, D: along the groove between the
source insert and the housing
FQG61/FQG62; order code 020, option K, L, M, N: along the thread of the proximity
switches and the three annular grooves on the cylinder housing
2. Have the samples analyzed by an authorized organization. A source is considered to be leaking
if more than 185 Bq (5 nCi) is detected in the leak test sample.
This limit value applies for the US. National regulations may specify other limits.
If the radiation source is potentially leaking, take the following action:
• Notify the radiation safety officer and follow his/her instructions.
• Take appropriate measures to prevent a potential spread of radioactive contamination from the
source. Secure the radiation source.
• Notify the competent authority that a leaking radiation source has been detected.
