A licensee providing mobile remote afterloader service shall—
Check survey instruments before medical use at each address of use or on each day of use, whichever is more frequent; and
Account for all sources before departure from a client's address of use.
In addition to the periodic spot-checks required by § 35.643, a licensee authorized to use mobile afterloaders for medical use shall perform checks on each remote afterloader unit before use at each address of use. At a minimum, checks must be made to verify the operation of—

Viewing and intercom systems;
Applicators, source transfer tubes, and transfer tube-applicator interfaces;
Radiation monitors used to indicate room exposures;
Source positioning (accuracy); and
Radiation monitors used to indicate whether the source has returned to a safe shielded position.
In addition to the requirements for checks in paragraph (b) of this section, a licensee shall ensure overall proper operation of the remote afterloader unit by conducting a simulated cycle of treatment before use at each address of use.
If the results of the checks required in paragraph (b) of this section indicate the malfunction of any system, a licensee shall lock the control console in the off position and not use the unit except as may be necessary to repair, replace, or check the malfunctioning system.
A licensee shall retain a record of each check required by paragraph (b) of this section in accordance with § 35.2647.
