  • Page 9: Introduction

    Model 4525 Gate Monitor Section Introduction The Model 4525 Radiation Portal Monitor (RPM) is a sophisticated system with very sensitive gamma and optional neutron detectors for detecting small amounts of radiation. The sophistication of the RPM provides the user with the best chance of avoiding radiation.
  • Page 10 Model 4525-10500 Model 4525-21000 The indoor wall-mounted Model 4525 computer uses software to display and store data from up to four Model 4525 RPMs via a 10Base-T Ethernet connection or 802.11g wireless connection. The software is composed of the following components: 1.
  • Page 11 Operator’s Manual Model 4525 Gate Monitor The software provides audible and visual indications of the current status of the RPMs. These include radiation alarms, background failures, power failures, low battery, and infrared failures. The software supports a network-attached camera, which allows an image to be captured when a vehicle enters or exits the RPM.

  • Page 15: Radiation

    Operator’s Manual Model 4525 Gate Monitor Section Radiation Radiation in recycled material has become a matter of growing concern. Whether the radiation is natural or artificial, the potential for injury and lost revenue in the workplace exists. For steel mills the threats of multimillion-dollar clean-ups, worker injuries, and lawsuits are staggering.
  • Page 16 Operator’s Manual Model 4525 Gate Monitor level varies as the inverse square of the distance from the source. For example, a source of a certain size will read a certain amount at a distance of one foot. If the distance is doubled (two feet from the source), the reading will only be 25% of that obtained at one foot.

  • Page 18 Operator’s Manual Model 4525 Gate Monitor Knowing a little bit about how the portal system works is important. One of the first things to learn is that there is a certain level of background or ambient radiation that is present all around us. Cosmic radiation is one source of this radiation, but a bigger contribution is from the dirt and rocks around us.
  • Page 19 Operator’s Manual Model 4525 Gate Monitor Therefore, if this vehicle drives off at the same time that another vehicle is within the portal, the radiation detector sees the increase in background radiation, and alarms. Our recommendation is for vehicles to stay out of the 3 m (10 ft) immediately before, after, and behind the detectors.
  • Page 20 Operator’s Manual Model 4525 Gate Monitor 7. Dirt and Scale: Some dirt and scale buildup has natural (NORM) radiation, and can set off the radiation alarm if enough is accumulated in the bottom of the trailer. Again, like above, the cause will only be revealed if the "empty"...
