• <strong>Monte</strong> <strong>Carlo</strong> plays an essential role in brachy<strong>the</strong>rapy<br />
dosimetry<br />
– calculates TG-43 parameters such as g(r), F(r,q),<br />
L (dose rate constant)<br />
• very hard to confirm <strong>the</strong>se calculations with much<br />
accuracy as experiments have large uncertainties (5%).<br />
• <strong>the</strong>re have been teams measure spectra from multiple<br />
seeds with reasonable consistency
