Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
At a minimum you need to be able to measure ambient radiation by type:

Sievert - Wikipedia, the free encyclopedia

Equivalency Weighting Factors[1] Radiation type and energy range Factor
electrons, positrons, muons, or photons (gamma, X-ray) 1
neutrons <10 keV 5
neutrons 10-100 keV 10
neutrons 100 keV - 2 MeV 20
neutrons 2 MeV - 20 MeV 10
neutrons >20 MeV 5
protons other than recoil protons and energy >2 MeV 2
alpha particles, fission fragments, nonrelativistic heavy nuclei 20
How are you going to do that "without a custom ready shiny instrument"?
