APPLICATION: Because of the extremely
high range capability of this instrument and the waterproof construction
of the ion chamber detection system, underwater monitoring (and in
hot cell monitoring) of Reactor Spent Fuel Elements, Reactor components
and doserate measurements of irradiated objects can now be made easily
and at the ranges called for at moderate cost.
GENERAL DESCRIPTION: The Underwater
Monitor consists of a lightweight single 6 AA cell operated, solid state
and MOSFET driven electronic package (Model CP-MU) coupled to a
High Range DMU-1 or Mid Range DMU-1000 Detector System consisting
of 60 feet of special low noise cable with a waterproof coupling to
a 8'' long x 1/2'' diameter aluminum tube containing an ion chamber
(in Model DMU-1) or 7-1/2'' long x 5-3/4'' diameter aluminum ion
chamber (in Model DMU-1000). A ``handle'' consisting of 8 foot
sections of free draining 5/8'' stainless steel tubing is available
as an option. Up to 16 feet may be used with DMU-1 in any position.
Twenty-four feet or more may be used vertically with DMU-1 or DMU-1000
chamber downward.
Four linear ranges on the electronic package provide
readings up to 1,000,000 R/hr. DMU-1000 and DMU-1 probes, when used
with CP-MU readout, extend the sensitivity of instrument so that levels
of 100 mR/hr to 1 million R/hr can be read. Both the high range and
low range probe can be used with the same readout. The scale multiplier
for the low range probe is 1 R/hr and for the high range probe is
1 kR/hr. A ``set'' position on the Range Switch permits the meter
to be adjusted to read zero by the zero adjust knob.
Calibration is fully adjustable.
The instrument case is made of drawn aluminum
with epoxy lettering for easy decontamination. Case openings are
sealed by gasket or screw closure for protection of electronics.
A reliable MOSFET electrometer circuit and improved
solid state electronics assure long uninterrupted service. Mechanical
switching of the high impedance circuit has been eliminated.
Protection against
influence by magnetic fields up to 60 gauss has been built into the
instrument. A top handle and four rubber feet achieve a more stable
base with no loss of display visibility.
