I'd bet it is long term exposure to cytotoxic chemicals. Cytotoxic chemicals and drugs scramble the DNA of cells, which always leads to cancer over long enough periods.
Radiation in hospitals is either nuclear medicine (cancer treatments) with very short half-life isotopes OR electrically generated high energy particles like X-rays (for imaging) or gamma rays. Both of those are stopped by lead sheeting in the walls.
In the case of nuclear medicine they do regular sweeps with a Giger counter and staff wear dose-meters, which detect radiation sources and exposure respectively.
In contrast cytotoxic chemicals last forever (!) and are not detected with a convenient hand-held device.
Historically most cancer clusters like this have been due to chemical exposure. Fire fighters, people cleaning jet fuel tanks, or working with organic solvents or chemicals.
I'll be very interested in seeing the results of the investigation.
