Replying to Jacob, "Uhm.. that's not what I was pondering Jacob. Both the Portable Scan Dihilator, and the Justicar suit have radiation detection sensors.. geiger counters, but their range is relatively short... only 60'ft in my suit, Dihilator perhaps a little more.. that's too short range for my purposes... I'm talking about wide-angle photography lens on the sensitive photo-cameras. The Justicar has such optical systems but the Dihilator has even bigger ones for wide angle shots."
"... LIGHT which falls on a photographic plate causes the crystals of silver halide, which form the essential constituent of the sensitive layer, to be converted by subsequent development to silver grains, and gives rise to a blackening of the exposed areas. The silver grains can be counted under the microscope, but they provide no direct measure of the incident energy. Although much painstaking work, culminating in the recent theory of Gurney and Mott, has led to a fairly complete understanding of the mechanism of the photographic process, many factors enter in to prevent the establishment of a one-to-one, or other simple, relationship between silver grains and absorbed quanta. Thus the photographic plate cannot be used as a method of absolute measurement of radiation: like the part played by the eye in visual photometry, its role is that of a null instrument for the measurement of an unknown source of radiation by comparison with a known. In addition, and unlike the eye, it provides a permanent record of brightness variations, often over an extended field."
... ... he pauses and seems to be looking off into nowhere for a moment as if wondering where what he just said came from?
Then he turns to Jacob a little embarrassed he translates, "Er.. I can take a wide angle photograph of Center City from high above with the Dihiliator and some appropriate film.. and the dark splotches will indicate sections of radiation quanta."
"...but they will be inaccurate and cover whole neighborhoods, but.. 'may' narrow down the search?"
