A trip to Wanamakers at Christmas (including eating in the top-floor restaurant and listening to scheduled organ concerts) was a treasured fixture of my childhood in the late 50s and early 60s. If I remember correctly, there was a monorail-like tram that ran around the periphery of the toy department too. Christmas lights festooned the facade of the organ.
Depending on the field, 3 Gy IS 'small' (with respect to doses to tissue during cancer treatment, which can be 60 Gy). Whole body doses of 1 milliGy in the environmental biz are considered worth examination. Even investigations of biomarkers for radiation exposure typically use doses in the range of 3 Gy.
I like this very much. BUT: What I cannot save I do not remember (quoth the Old Guy). Any way to save these images as SVG. (Screen grabs are less satisfactory.)
Shell dependencies for install?
Got:
bash-3.2# just package && mv dist/infat* /usr/local/bin/infat # Wildcard because output name includes platform
bash: just: command not found
No dependencies for install, just is the command runner I use to keep things organized, it's a replacement for make(1). If it hurts to download just, you can build using SPM:
just is a great command runner[1], not a shell script. Looks like it is needed if you build from source or install from Github releases. Alternatively, use `brew install philocalyst/tap/infat`(haven't done it myself but I bet it has just as a dependency anyway)

I welcome the new library!
I have used a RadiaCode 103g for more than a month. I also have a more conventional NaI:Tl 5cmX5cm scintillator+PMT in my basement with 95 lbs of lead shielding (as lead shot). I'm painfully familiar with detector drift and recalibrations required with conventional (amateur) detectors. In my opinion the RCs are game changing: their calibration ranges from good to excellent, in that I can import a spectrum into the (exceptionally useful free Sandia National Labs) tool InterSpec, extremely quickly identify peaks and the relevant radionuclides. The RC is very compact with a well-defined detector volume (because it IS relatively small). If there is a weakness, it is that it's mostly targeted toward running on a smartphone and support for iOS vs. Android has lagged a bit, though very recently an excellent update has appeared for iOS. I have tested in on a variety of spectra (137Cs, 232Th, 60Co, 133Ba) and for long background counts and am quite happy with the resolution and stability.
I have yet to use its interface to GPS data (I already have a bGeigie Nano built from a Safecast kit). Its impact is that almost everything one might like--count rates, dose rates and net dose, data logging, and GPS interface is all there in a sub pocket-size unit.
As noted, ordinary maps may suffer (for example, in epidemiology)from the impact of a very non-uniform population density. A disease cluster then MAY be a cluster, or it may be ordinary disease rates in a highly populated area. In my limited experience a cartogram is a deliberate distortion of the SHAPE of a map region in order to make some property (say, population DENSITY) constant everywhere in the new region. Then anomalies jump out. Done with care, one can do careful statistics within the cartogram and then back-transform to get statistics for the original map area.
