Introduction

1.1 Product Description

The Model 1060 is a smart radiation detector. It is a printed circuit board that supports a wide variety of "front end" radiation detectors and provides electronic digital and analog information about the radiation environment to users.

The Model 1060 collects, interprets, analyzes, stores and communicates radiation detector data from virtually all pulse generating radiation detectors such as Geiger Mueller tubes, proportional tubes, boron tri-fluoride tubes, and photo-multiplier tube/scintillators. To support these radiation detectors the 1060 provides a wide range high voltage suitable to operate most radiation detectors.

In addition, it will simultaneously accept up to 8 analog and 16 digital inputs.

The 1060 provides digital outputs, and is a good citizen on a network. It operates independently or as a member of a larger system.

It is configured by the user through serial software commands, either locally or remotely.

It defaults upon power up or reset to predetermined operational characteristics that can be established and altered by the operator. Such defaults are stored in a non-volatile memory.

The Model 1060 is only 2.8 in x 8.8 in (7.11 cm x 22.29 cm) in size and therefore requires a very small space for mounting. It can be mounted in a variety of enclosures for many different environments.

It provides, via digital communication, raw and conditioned data from any or all of the inputs. It performs a wide variety of calculations on raw data, such as conversion to engineering units, and boxcar or exponential smoothing of data.

Optionally, it can be programmed to make local decisions based upon input data. The available area monitor models are shown below:
