A Nuclear Densometer Test is a field test used in geotechnical engineering. The test is performed on a compacted base to establish its percentage of compaction. With the use of a 3/4" diameter rod a hole is created in the compacted base by hammering the rod into the base to produce a hole that the densometer's probe can be inserted into. 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. The densometer measures the amount of radiation that returns to it through the compacted soil and determines the percentage of compaction based on the amount of radiation received.
