Wall contamination mapping using a binocular camera

The binocular camera with its dual head configuration allows to estimate the true distance to a radiative source using gamma emission triangulation.

This opens the way to quantitative imaging of contamination.

A first trial has been done in a decommissioned power plant.

The maximum activity on the wall was 0,2uSV/h (red spot).

The gamma FOV (76°) is slightly smaller than the optical image (90×90).

The dose calculated fits the 2 known points (0,2 & 0,18 uSV/h) values are calculated on other points of the image.
