Abstract |
This dosimeter has been validated over the range of 1.8 to 164ppm-h (0.23-21 ppm H2S for 8h). Analysis is based on the Texas Air Control Board's molybdenum blue colorimetric method; colour-activated exposed badge solutions are read out on a spectrophotometer set at 580nm and using 10mm cells. The overall accuracy is ±16%; variations in temperature (10-40°C), relative humidity and face velocity (0.6-76m/s) do not affect badge performance. Unexposed badges are stable for 12 months refrigerated or 2 months at room temperature. Exposed badges can be stored for 1 week at room temperature or 1 month refrigerated. There are no significant interferences from other contaminants. |
