Many cobalt and x‐ray therapy machines use mechanical timers to control the given dose. There is no other timer on the machine to verify that the correct time was set or that the timer did not malfunction. This article describes a digital timer that has been installed on the MIR therapy machines as a lapsed‐time indicator.
