Dose Distributions of an ¹⁹²Ir Brachytherapy Source in Different Media

Figure 4

Radial dose ratio calculated by MCNPX code with the ¹⁹²Ir microSelectron HDR source centered in three spherical tissue phantoms with a diameter of 30 cm. The red line represents the dose ratio of lung to water; the green line represents the dose ratio of bone to water.
