ANTECH

Model 2004-Passive Neutron Curium Monitor

Benefits

· Simple, non-quantitative, low cost system for

the detection of the presence of curium

(principally 244Cm) in waste drums, boxes

and crates

· Small footprint, floor mounted detection

module or wall mounted (with brackets) for

ease of use and economy of space

· Module dimensions:- 1100 mm x 200 mm x

80 mm (43.3" x 8" x 3")

·  The moderator block is clad with a skin of

aluminium sheet for ease of decontamina-

tion.

·  A junction box for the four tubes is housed at

the top of the module and combines and am-

plifies the detector signals and distributes

high voltage to the detector tubes

·  Provided with User Manual and Test Docu-

mentation

·  Weight (excluding wall mounting brackets)

= 21 kg (46.2 lbs)

3

·  Four He-3 detector tubes, 25.4mm x 1.0m at

4 Atmospheres

·  Multiple Curium monitors can be adapted for

directional application where background

subtraction is required

Features

Suitable for use with stand-alone counting electronics, Advanced Multiplicity Shift

·

Register (AMSR-150)

· Robust Construction for operation in laboratory or plant

· Four 3He detector tubes (25mm diameter x 1meter length, 4 atmospheres 3He fill pres-

sure with HN connectors) in a rectangular high-density polyethylene block

·  Inspection and testing includes measurement of High Voltage bias curve, discrimina-

tor and gain setting and thermal neutron die-away time

·  Count rate produced by a Cf-252 source (with certified activity) positioned at one me-

ter from the mid-height of the detector module is recorded

· Provides a curium monitoring system when used with the ANTECH Advanced Multi-

plicity Shift Register (AMSR 150)
