I don't know when blood irradiation started, might be a source of Cs-137 in one of those units.

Moisture density gages, used in construction, have both Cs-137 and Am/Be-241, for density and water content measurements.  These sources are not that large, say 10mCi Cs-137 and 40 mCi Am-241.  The fact that it is an old air base would mean that there was a specific need for these units, maybe several in storage onsite.  There was a big SNAFU at the current Denver airport during its construction, someone read the wrong side of the moisture curve, messed up the runway, had to re-build it.  I don't know what units were available in 1983, Troxxler is a good mfg to look up.  The beta, gamma, alpha and maybe neutron presence would complicate/confuse the initial responders in their first assessment of the hazard.  That would be the point of using the Am-241, not big enough to be dangerous, but throws a curve at the government's response, alphas may mean U or Pu, much more scary to the public.  Remember Alexander Litvinenko, they didn't think to look for alpha emissions when they "checked" him for radiation poisoning.

My questions is what radionuclides would the Nuclear Medicine Department in a British hospital in 1983 that would be suitable for contaminating a deactivated air base so the USAF cannot deploy a new nuclear missile weapon system there?
