There lies my question: given that this happens on land (not in space), would the Hawking radiation irradiate the environment as a dirty bomb or nuclear meltdown would? Is Hawking radiation "dirty" or will the blast just ash everything within a coupla miles radius?
The existing comments show that the blast radius would be absurdly greater than what I need so ... related query. Suppose, instead of a black hole, the object is compressed into neutronium. Would that reduce the blast radius?
