Process Engineering Section – Instrumentation and Automation Section – Daily Question – Question from 2020-10-30: Discussion question: 281. When the level of material measured by a radiation level gauge is at its highest, the gauge’s indication is also at its highest. At this time, is the radiation received by the probe strongest or weakest? Why?
When the level of material in the ray level gauge is at its highest, the gauge’s indication is also at its highest; at this point, the rays received by the probe are the weakest. Because as the height of the material increases linearly, the radiation dose at the probe area decreases exponentially; when the material height reaches a certain value, the radiation dose from the source at the probe area essentially disappears, and the total dose approaches the background level.
It is the weakest, because the contact area is large; thus, the absorption rate decreases as the area increases

The probe receives the weakest radiation; since the contact area is large, the absorption rate decreases as the area increases.
The probe receives the weakest radiation, as the radiation has to penetrate through the greatest thickness of material, resulting in the most energy being absorbed; by the time it reaches the receiving end, its energy has been significantly reduced.

When the level of material in a radar level gauge is at its highest, the gauge’s indication is also at its highest. At this point, the radiation received by the probe is weakest, as radar level gauges operate by utilizing the material’s ability to block radiation; the more material there is, the greater the obstruction, and thus the weaker the radiation received by the probe
