Summary

Relative radiant power at the detector against distance in clear air, set to 1 at 40 m. Halving the distance gives four times the power. Based on Schifiliti et al. (2002), pp. 4-31 to 4-32.

Original vector illustration for Flame detector, level 2 Intermediate.

Source basis: Schifiliti et al. (2002), p. 4-31 (inverse square law) and p. 4-32 (40 m nominal detection distance in the hangar example)
Alt text: Falling curve of relative radiant power against distance from 10 to 60 m, equal to 1 at 40 m and 4 at 20 m.
