Percentage depth dose measured with and without the BC-620 reflective paint. (a) The direct comparison between the light output, as measured under both conditions. The scale is the integrated signal output, which is arbitrary but comparable for similarly collected data. (b) Both responses normalized to 20 mm depth and compared with a PinPoint N31014 ionization chamber. (c) The percentage difference between the two sets of FOD data. Error bars shown are the 95% confidence intervals from the three measurements at each depth. The error bars on the IC data were negligible and have been omitted. |
