    - Portable Nuclear Density/Moisture Gauge Use and Safety Training This is the initial course for individuals who need to be certified to use a portable nuclear gauge. This certification will allow you to transport and use the nuclear gauge in compliance with the NRC regulations. Warm up the nuclear gauge in accordance with the manufacturer’s recommendations. 4.

Portable gauges are used in industries such as agriculture, construction and civil engineering to measure parameters like the moisture in soil, and the density of asphalt in a paving mix. As these contain radioactive material, the use and possession of the Nucleonic Gauges need to be regulated.

DEFINITION. A nuclear gauge (also called a nuclear density gauge, a soil moisture gauge, or a moisture density gauge) is a tool used for civil engineering projects and construction that measures soil density or soil water content.

Nuclear gauges are also used for.

DETERMINING FIELD DENSITY & MOISTURE CONTENT WITH THE NUCLEAR GAUGE. The Nuclear Moisture Density device (or Nuclear Gauge) is specifically designed to measure the moisture and density of soils, aggregates, cement, and lime treated materials, and to measure the density of asphalt concrete.

Compaction Tests Made With Nuclear Moisture Gauges June A report addressing the use of the moisture correction when using any nuclear moisture gauge, focusing on the B.

Introduction It has become increasingly evident that many nuclear gauge users are neglecting an important “fact of life” in the compaction testing of Size: 27KB. A standard block is used to give a quick check of the gauge’s ability to measure density and moisture.

While in the standard mode the gauge will test the number of density and moisture counts received by the detector tubes. The number of counts are compared to previous standard counts. This guide describes the process and objective of calibrating the water content system of a nuclear surface moisture and density gauge, or formulating the mathematical relationship between the water content system response (the “water content count”) of a nuclear surface moisture and density gauge and the corresponding water mass per unit volume value of the water content standard upon.

The Moisture and Density standards should be logged in a field book stating the date and readings, location and the test material. This builds up a history over a period of time and can identify if the machine is faulty. This Density/Moisture Gauge, the HSSD, is specifically designed to measure the moisture content and density of construction materials.

The microprocessor-based units automatically computes these parameters and makes corrections to the measurements. It uses the attenuation of gamma radiation due to Compton scattering andFile Size: 2MB. of nuclear density gauge for determination of moisture and density of subgrade soil in its Quality Assurance Handbook for Rural Road volume-II (Equipment and Test Procedure) in section (c).

Portable nuclear moisture/density gauges in the construction industry This leaflet is aimed at employers of those people working with portable nuclear moisture/density gauges, and the self-employed.

It may also be helpful to those managing road-building or repair projects where these gauges. gauge cannot be used, the methods described in "Test Method for Earthwork Compaction Control by Sand Cone or Volumeter Apparatus," or any other method approved by the Department shall apply.

Warm-up and check the equipment. Daily Most nuclear gauges require a warm-up. The Nuclear Gauge Testing Manual (NGTM) provides procedures and instructions for the safe use and operation of nuclear gauges to measure the compacted density of soils, crushed rocks, concrete and asphalt materials.
