1703M OPERATING MANUAL nukeALERT II MODEL 1703M This manual is intended to describe the design, operation and use of our Personal Radiation Detector (PRD) 1703M. The Operating Manual includes the general description, specifications of the detector, as well as other information necessary for the proper operation of the detector and understanding of device capabilities.
1703M OPERATING MANUAL 1. APPLICATION The Personal Radiation Detector (PRD) Model 1703M is designed to search, detect, and locate gamma and/or neutron emitting radioactive sources. The instrument is carried on a belt clip and may be used both indoor and outdoor by various users whose professional duties involve detection and location of radiation sources. The instrumentʼs operating history is stored in its non-volatile memory and may be transferred to a personal computer through an infrared (IR) interface.
1703M OPERATING MANUAL 3. GENERAL DESCRIPTION 3.1 Introduction The 1703M is an easy-to-use instrument with only two buttons (Figure 1). To operate the instrument the user does not need to be an expert in nuclear physics or radiation protection. After being switched ON, the instrument works passively and automatically and alarms when it detects a radiation source (gamma emitting isotopes).

1703M OPERATING MANUAL The instrument operates in two modes: detect mode and search mode. Instrument control is shown in Figure 3. The instrument has an automatic low battery detection circuit. If the voltage drops below 1.115 V, the battery discharge warning sign is displayed in the LCD lower left corner and an audible alarm different from a radiation alarm, sounds. In this case, the battery needs to be replaced (see section “Battery replacement”). The instrument also controls detector blocks.

Dose Rate Values Number 0 1 2 3 4 5 6 7 8 9 Dose Rate Range From background to 34 µR/h ≥34 to <38 ≥38 to <43 ≥43 to <69 ≥69 to <140 ≥140 to <169 ≥169 to <550 ≥550 to <942 ≥942 to <1370 ≥1370 The analog scale and the light and audible alarms are activated simultaneously. The number of segments filled on the analog scale is proportional to the number displayed on the LCD.
1703M OPERATING MANUAL PC communication PC communication functionality is an option designed for advanced users. The instrument can communicate with a PC when the “LIGHT” button 2 is pressed.
1703M OPERATING MANUAL 4. OPERATING INSTRUCTIONS FOR THE USER The instrument is intended to search, detect, and locate gamma emitting radioactive sources. 4.1 Detection of Gamma Radiation Sources Turn the instrument ON by pressing the “MODE” button 1. The 1703M LCD displays the gamma dose rate. When a radioactive source is detected (the preset thresholds for gamma are exceeded), the instrument produces the visual and audible or vibratory alarms.
1703M OPERATING MANUAL 4.3 Communication with PC For communication with a PC it is necessary to use a PC with IrDA port or IR adapter and application program PM17XX_14XX supplied on the installation CD. Minimum system requirements: P100 32 Mb RAM Windows 98, 2000, XP (small font in Windows settings) 2 Mb free on the hard disk and adequate space available to install the database 800X600 monitor resolution To install the application program, insert the installation CD and run the SETUP.EXE program.
1703M OPERATING MANUAL 5. TROUBLESHOOTING Table 2. Actions to take if instrument is not operating properly. Problem Possible Cause Solution 1. Gamma detector block failure 2. Processing block failure Return instrument for repair. Return instrument for repair. 1. A gamma radiation source is too close to the unit 2. Gamma detector block failure 3. Processing block failure Remove the source or step back 1 foot at a time until the “OL” message goes away Return instrument for repair.
