Thermal dose unit
A Thermal dose unit (TDU) is a unit of measurement used in the oil and gas industry to measure exposure to thermal radiation. It is a function of intensity (power per unit area) and exposure time.[1]
1 TDU = 1 (kW/m2)4/3s.
Results of exposure
| Level of Exposure | Result | |
|---|---|---|
| Mean | Range | |
| 92 | 86-103 | Pain |
| 105 | 80-130 | Threshold First Degree Burn |
| 290 | 240-350 | Threshold Second Degree Burn |
| 1000 | 870-2600 | Threshold Third Degree Burn |
