Webradiation [9, 10]. Once he found that the radiation had a thermal spectrum, he realized that it did make Bekenstein’s idea consistent, of a ﬁnite black hole entropy proportional to area, though not Bekenstein’s conjectured value for η. In fact, Hawking found that the black hole temperature was T = κ/(2π), so ǫ = 1/(2π) and hence η ... • S.W. Hawking, Nature 248 (1974) 30: il primo articolo di Hawking sull'argomento • D. Page, Phys.

WebIt does not emit radiation because if it were, it would have to decay to some lower-energy state. This eventually may happen when the proton decays, but the radiation is not black-body radiation, so it can't be considered Hawking radiation.
