After reading the comments, if there is a higher rate of radiation than should be, maybe the missile is the culprit. Low grade nuke blowing up an arms depot is a good idea to hide the fact the missile was a mini-nuke.
Just thinking.
well, I learned a bit. Gamma radiation was released and it’s the quantity.
“Effects of Nuclear Weapons. Nuclear Radiation. The release of radiation is a phenomenon unique to nuclear explosions. There are several kinds of radiation emitted; these types include gamma, neutron, and ionizing radiation, and are emitted not only at the time of detonation (initial radiation) but also for long periods of time afterward (residual radiation).”

Isotopes of natural uranium decay by emitting mainly alpha particles. The emission of beta particles and gamma radiations are low. The table below shows the average energies per transformation emitted by U-238, U-235 and U-234.
Isotope Average Energy Emitted Per Transformation (MeV Bq-1)
-———Alpha-——Beta-——Gamma
U-238-—4.26——0.01——0.001
U-235-—4.47——0.048-—0.154
U-234-—4.84——0.0013—0.002
