The Digital Radiation Monitor measures alpha, beta, gamma, and x-ray radiation.
This chapter briefly describes the Digital Radiation Monitor's functions. For more
information on how to use the Digital Radiation Monitor, see Chapter 3,
"Operation."
The Digital Radiation Monitor counts ionizing events and displays the results on the
liquid crystal display (LCD) (
4
). You control which unit of measurement is shown
by using the mode switch.
Whenever the Digital Radiation Monitor is operating, the red
count light
(
1
) flashes
each time a count (i.e., an ionizing event) is detected.
