Air kerma measurements in air with Landauer nanoDots should therefore be conducted with beam energy appropriate buildup, both in Cs-137 and definitely in Co-60 beams so that the signal on the nanoDots originates solely from electrons that were liberated either in the buildup or in the materials of the detectors themselves.
The inverse square calculation is as follows:Where: 2= � �∙ ESAK = corrected x-ray air kerma at the skin entrance without backscatterSDD = source to center of radiation detector distanceSSD = distance from the source to the surface of the skin (approximately SID minus the patient thickness)K = measured air kerma NOTE: Air kerma (mGy) may be converted to exposure (mR) by dividing by 0.00876 mGy/mR.
Air kerma is a radiation quantity that is used to express the radiation concentration delivered to a point, such as the entrance surface of a patient's body.
Air kerma was scored in a spherical voxel of 20 cm diameter centered at x=1.3 m along the vertical direction from the source to the shield, using anF6 photon energy deposition tally.
