Webb30 okt. 2024 · To validate the beam source models, we compared the percentage depth dose (PDD) and beam profiles of 4- and 6-MV x-ray beams in water (50 × 50 × 50 cm 3) for 10 × 10 cm 2 field and 100 cm source-to-surface distance between the PHITS simulation and TPS. The photon and electron cutoff energies were, respectively, 10 keV and 100 keV. Webb"Protective curtain" was the physical experiment onboard the International Space Station (ISS) aimed on radiation measurement of the dose - reducing effect of the additional shielding made of hygienic water-soaked wipes and towels placed on the wall in the crew cabin of the Service module Zvezda. The measurements were performed with 12 …
