Radalert 100X™ Nuclear
Radiation Monitor
|
|
|
|
The
Radalert 100X™ measures alpha, beta, gamma, and
X-radiation. Its digital display shows
|
|
readings in your
choice of counts per minute (CPM) µSv/hr or mR/hr
or in accumulated counts.
|
|
A
red LED blinks and a beeper chirps with each count (the chirp can be muted).
An audible
|
|
alert sounds
when the radiation reaches a user-adjustable level.
