An x-ray tube has a total filtration of 3.0 mm Al and HVL of 2.5 mm Al, and emits 1.8 mGy. Therefore: A 1.2-mm-diameter tube is inserted into an unknown liquid whose density is. Verified answer.

HVL can also be expressed in terms of air kerma rate (AKR), rather than intensity: the half-value layer is the thickness of specified material that, "attenuates the beam of radiation to an extent such that the AKR is reduced to one-half of its original value.
