Has anyone seen links to actual spectra from the monitoring organizations' counters? An example of the sort of thing I'm looking for: https://arxiv.org/pdf/1103.4853.pdf (see Figure 1)

LHC is a science experiment. Its job is to, first, check older results [1], and second, put nature to the test in a well-motivated and important way. In particular, LHC is the Higgs hunter, a messy [2] pathfinder before a precision Higgs-studying tool. It succeeded at that job [3]. That LHC has found no new physics beyond the standard model is not a failure. Finding nothing where you thought you might find something is as useful as finding something. If anything, it is more interesting, as it means there is still far more to be learned. Politics are about people. The science case is a driver…

The scientific article behind this is interesting; it is at http://arxiv.org/abs/1103.4853 Quick summary: the researchers in Seattle take the building's air filters once a day, compress them into a block, stick the block in a lead vault, and use a gamma-ray analyzer on it. They can detect radioactive particles from Japan, 7 days later (at very low levels). Based on the composition, they believe the particles are from radioactive steam, not burning fuel, which is kind of interesting. Because they are analyzing the filters, rather than the air directly, they are testing particles from 114,000…
