Statistical properties of blackbody radiation are discussed by the techniques of second quantization. Various probability distribution functions are derived, in particular the Bose-Einstein distribution function and its generalization for an arbitrary number of momentum-spin states. The Sudarshan phase space distribution function for blackbody radiation is obtained. Although in general the Sudarshan distribution function appears to be a generalized function, it is found that for the radiation field considered here, it becomes an ordinary function and is in agreement with expressions derived recently somewhat heuristically by other authors. A certain new probability distribution function for a statistcal radiation field is introduced and is expressed in terms of the eigenvalues of the annihilation operator. Unlike the phase space distribution function of Sudarshan, this function is non-negative. Finally an expression is derived for this probability distribution function appropriate to blackbody radiation.
