Fracking perf-gun explosion.
http://www.ksat.com/news/Two-oilfield-workers-critically-injured-in-explosion/-/478452/18143774/-/xy0at1/-/index.html
Extremely hot, high pressure, high explosives used. (RDX, HMX, HNS)

Whoa, what's the "Blended Powdered Metal Liner" stuff on page 5? (*)
Turns out blast pressure can be on the order of 10-20 MILLION PSI.
Amazing these guys lived.
Whoops! Check this...
Obama's AG Eric Holder authorized the frackers to store these high explosives OUTSIDE a bunker.
Huh? WTF, ATF?

(*) They don't actually say Depleted Uranium... still it's the ideal material for that.
Same reason they use DU in anti-tank munitions.
Burns super hot, and it's very hard. Think about the pressures needed
to overcome being under 7,000' of granite (~10k psi) and also
to pierce steel pipe (another 10k psi).
Might be another source of radiation in addition to
a) NORMs in drill cuttings, radon gas, b) radioactive sand

c) radioactive rods used to locate gas

d) And now (my well informed guess) they are using DU in the perf gun shaped charge
