 note = {application/pdf, 論文(Article), The purpose of this study was to calculate the replacement correction factor, P_<repl> (the product P_<gr>P_<fl> in the AAPM's notation, or the product p_<cav>p_<dis> in the IAEA’s notation), at a reference depth, d_<ref>, for cylindrical chamber cavities in clinical photon and electron beams by Monte Carlo simulation. P_<repl> was calculated for cavities with a combination of various diameters and lengths. P_<repl> values calculated in photon and electron beams were typically higher than those recommended by the TG-51 and TRS-398 dosimetry protocols. P_<repl> values for a Farmer chamber cavity were higher by 0.3 to 0.2% and by 0.7 to 0.4%, respectively, than data of TG-51 and TRS-398, at photon energies of ^<60>Co to 18 MV. Similarly, the P_<repl> values for electron beams were higher by 1.5 to 1.1% than data for both protocols, in a range of 6-18 MeV. The P_<repl> values depended upon the cavity diameter and length, especially for lower electron energies. We found that P_<repl> values of cylindrical chamber cavities for photon and electron beams were significantly different from those recommended by TG-51 and TRS-398., http://link.springer.com/article/10.1007%2Fs12194-012-0154-5},
