Abstract
Apparatus for radiation mapping of a region comprises a spectrum analyzer for analyzing a local radiation field according to wavelength, and a positioning unit for obtaining a position reading to correlate with said local radiation field, thereby to provide said radiation mapping. The results may be provided as layers to a map, and different layers may be provided for different frequencies and different times of the day.

9. A method of mapping a region for local radiation levels, comprising:
-
moving through said region; at locations in said region detecting and analyzing a spectrum of interest for radiation levels over said spectrum; associating each location analysis with an indicator of said location; associating each location analysis with a sampling time; and using said location indicators, superimposing said analysis on a map of said region. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of mapping a radiation spectrum of interest to a region of interest, radiation levels in said spectrum obeying a periodicity, said periodicity defining a period, the method comprising:
-
obtaining samples at locations in said region at frequency intervals in said spectrum, each sample being obtained at a certain sample time, for each frequency at said sample time, using said periodicity to extrapolate said sample to said period, adding each of said extrapolated samples to a geographical map of said region of interest, as a series of layers on a time dimension, such as to provide a layer on said geographical map for each frequency time combination. - View Dependent Claims (17, 18)
