BORON LOADED MODERATOR
ENERGY RESPonSE GRAPH
The Model 5085 Meridian is a highly evolved neutron REM meter of classic design. It is an ideal portable instrument for measuring neutrons in reactors, laboratories and hospitals. The Meridian has a wide energy response and closely conforms to the ICRU REM response curve.

The autoranging display has both a digital readout and a bargraph that simulates a moving pointer. The display is mounted on top of the moderator which makes it easy to see when it is being carried. The display also rotates in 2 axes and can be placed at either end of the moderator; it can be separated for a remote readout. No matter where you place the moderator, you can usually move the display so you can read it.

The moderator is a classic boron loaded Anderson Braun design. One end of the moderator is rounded to give better directional response. In the moderator, the detector cable passes through a labyrinth to eliminate streaming. The standard Meridian has a Bf3 detector; a He3 detector is also available which offers more sensitivity. The instrument may be carried with the rounded end or the flat end toward the front with the display moved accordingly.
