선형가속기의 6MV X선에 대한 소형조사면의 선량측정

Dose Characteristics of Small Radiation Fields for 6MV X-ray of Linear Accelerator

Radiation dosimetry has been extended to small fields less than 4×4 cm² which may be suitable for irradiation of small intracranial tumors. Special consideration was given to the percentage depth dose and scatter correction factors with 0.14 ml ion chamber, film dosimetry and TLD measurement. Calculated dose distributions were compared with measured data.
