METHOD OF REAL-TIME MAPPING OF A DISTRIBUTION OF PHOTONS IN A SITE

摘要

The invention concerns a method of real-time mapping of a presence distribution of a source of photons in a site, the method comprising the steps consisting of measuring (100), at a plurality of measurement points, a photon flux in an energy band-width determined with a spectrometric detector, and noting the geographical co-ordinates of said point, and, at each measurement point, —from a response function of the detector, and information on the site, establishing a distribution of origins (200) of the photons around the measurement point, —from the distributions, representing (300), on a map of the site, a distribution of origin of photons, the method further comprising, for each measurement point starting from the second, a step (250) prior to the representing step (300), during which the distributions of origins of the photons around the current measurement point are correlated with those of previous measurement points.

1. A real-time cartography method of distribution of the presence of a source of photons in a site, the method comprising steps consisting of measuring (100), in a plurality of measuring points, a flow of photons in a determined energy band with a non-collimated spectrometric detector, and logging the geographic coordinates of said point, and in each measuring point,
from a response function of the spectrometric detector, and information on the nature of the site, setting up distribution of provenances (200) of photons detected around the measuring point, from the distributions of provenance around measuring points, representing (300) distribution of provenances of photons on a map of the site, the method further comprising, for each measuring point from the second, a step (250) prior to the representation step (300), during which the distributions of provenances of photons around the current measuring point are correlated with those of previous measuring points.
