2. Using the Piranha Dose Probe Holder Note! If you want to have the cable of the Dose Probe running through the holder, you need to mount it (starting with the detector side) from the inside of the holder sideways through the narrow opening. Note that you will need to pull out the carbon pipe to make room for the Dose Probe to pass. -
Page 8: Setup For Rad And Flu Above Table Measurements
A typical setup for measurements in radiography and fluoroscopy with the Piranha DPH directly on the table, is shown below. Note: The Piranha Dose Probe is directionally sensitive, thus the detector surface should be facing upwards for radiation coming from above the table.

R100B An example: When comparing the Dose Probe from RTI to a Radcal 180 cc at RQC 5 (70 kV and 2.83 mm Al + 1.5 mm Cu) a relative difference of 8 % (1.02 - 0.94) can be read out from the graph above. An additional 6 % is added due to the scattered radiation that is not registered by the Dose Probe.
