    The Model 3440 gauge utilizes two modes of operation: direct transmission mode (with the source rod extended into the material) and backscatter mode. Figure 2 and Figure 3 illustrate these two modes of operation. WARNING! The source rod should always be locked in the SAFE position when the gauge is not in use.

  • Page 21: Moisture

    The Model 3440 gauge uses a 40 mCi (1.48 GBq) Americium-241:Beryllium neutron source to measure the hydrogen content (consequently the water content) of the material. Neutrons emitted by the Am-241:Be source penetrate the material and are thermalized (or slowed). Thermalization is the process where neutrons are slowed to the point where further collisions with hydrogen or other materials will not continue to slow the neutron.

  • Page 39: Taking The Standard Count

    The Model 3440 gauge uses a Cesium-137 and an Americium-241:Beryllium source for taking measurements. These radioactive sources undergo a natural decay process, resulting in a gradual loss in the intensity of their radiation. The time required for the source strength to diminish by 50% is referred to as the half-life.

  • Page 75: Target Menu

    The Model 3440 gauge uses operator-specified target values to determine the percent compaction after determining the density of the test material. Target values include Gmb (Marshall), Proctor, and Gmm (Voidless density) values. The gauge uses the Marshall and/or voidless density values to calculate the compaction level in the Asphalt mode.

  • Page 76: Target Values

    NOTE Because the menus for managing the Gmb (Marshall), Proctor, and Gmm (Voidless density) values are essentially the same, the following sections describe Gmb (Marshall) only the menu.

    The moisture offset (k) is determined by comparing the moisture of a laboratory sample with the gauge moisture reading. The gauge allows the operator to enter the moisture offset manually, or to have the gauge derive the moisture offset. The gauge can store up to four moisture offsets. To access the Moisture Offset menu, press 2 at the Offset menu shown on page 7–2.
  • Page 84 Enter a Moisture Offset (Manual Entry) To enter a new moisture value manually via the keypad, first determine the true moisture content of a sample taken at the measurement site using standard laboratory methods (for example, oven drying, and so on).

  • Page 87: Trench Offset

    To use the gauge in a trench or within 0.6 m (2 ft.) of a large vertical surface, first perform a trench offset. The trench offset adjusts all moisture measurements and density measurements from backscatter to 4 inches. For direct transmission measurements over 4 inches deep, the gauge will only adjust the moisture measurements.

  • Page 145 Types of Radiation The radioactive sources in the gauge produce four types of radiation: Alpha particles Beta particles Gamma rays (photons) Neutrons The alpha and beta particles are stopped by the source capsule. Therefore, they present no external hazard to personnel. Only the gamma and neutron radiation from sealed sources contribute to any occupational radiation exposure.

  • Page 146: Radiation Safety

    This section discusses the principles of general radiation safety. This information includes specific procedures for operating, inspecting, cleaning, and leak testing the gauge to ensure safe operation. Radiation Dose Radiation cannot be detected by any of the human senses (sight, touch, hearing, smell).

  • Page 147: Figure 15. Effect Of Distance On Exposure

    Limiting Exposure Under average conditions, an individual working with the gauge will receive less than 200 mrem per year. A basic principle of radiation protection is that radiation exposure should be kept as far below the limits as is reasonably achievable.

Troxler offers NVLAP- certified personnel monitoring services using TLD badges. In Canada, nuclear gauge users are not normally classified as Atomic Radiation Workers.
  • Page 149 Source Rod Inspection To ensure the integrity of the source rod, Troxler recommends that a qualified Troxler service person inspect the gauge and the source rod at least once every five years. This inspection includes checking for excessive wear, corrosion, or damage that could affect the safety of gauge operation.
  • Page 150 Daily Inspection The gauge should be inspected daily before use to ensure proper operation of all safety features as follows: The source rod opening in the bottom of the gauge is equipped with a spring-loaded tungsten sliding block that shuts when the source rod is in the SAFE (shielded) position.
