March Learn how and when to remove this template message A nuclear densometer is a field instrument used in geotechnical engineering to determine the density of a compacted material. Also known as a soil density gauge, the device uses the interaction of gamma radiation with matter to measure density, either through direct transmission or the "backscatter" method. The device determines the density of material by counting the number of photons emitted by a radioactive source cesium that are read by the detector tubes in the gauge base.

March Learn how and when to remove this template message A nuclear densometer is a field instrument used in geotechnical engineering to determine the density of a compacted material.

Also known as a soil density gauge, the device uses the interaction of gamma radiation with matter to measure density, either through direct transmission or the "backscatter" method.

The device determines the density of material by counting the number of photons emitted by a radioactive source cesium that are read by the detector tubes in the gauge base.

A second time interval is typically used for the counting period. A nuclear densometer is used on a compacted base to establish its percentage of compaction. Standard counts are the amount of radiation released by the two nuclear sources inside the machine, with no loss or leakage.

This allows the machine to compare the amount of radiation released to the amount of radiation received. The densometer is placed on top of the hole, and then the probe is inserted into the hole by unlocking the handle at the top of the probe. One source produces radiation that interacts with the atoms in the soil, and is then compared to the standard count, to calculate the density. The other source interacts with hydrogen atoms to calculate the percentage of water in the soil.

In direct transmission mode, the source extends through the base of the gauge into a predrilled hole, positioning the source at the desired depth.

The high-energy neutrons are slowed when they collide with hydrogen atoms, and the detector then counts the "slowed" neutrons.

Sabei This last function involves a certain level of risk due to the emission of radioactivity, which is why the regular maintenance and calibration of the instrument is of extreme importance. Nuclear meters containing radioactive sources desnimetro gamma are widely used in the oil and gas, chemical, nuclear, petrochemical and many other industries. Can I make a topic hidden or private? Nuclear energy provides Troxler Calibration medicine with specific diagnostic procedures, which are commonly used today.
