Thermal dose unit explained

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
