The instrument or dosimeter must be checked with a dedicated check source for proper operation at the beginning of each day of use. The licensee must keep a record as described in section (4) of this rule.

(7) If a radiation monitor is inoperable, the licensee must require any individual entering the teletherapy room to use a survey instrument or audible alarm personal dosimeter to monitor for any malfunction of the source exposure mechanism.
