Details are given for some kinds of nuclear emulsions which can be prepared by simple laboratory methods. The characteristics of these emulsions have been compared with Ilford nuclear emulsions. The properties of proton sensitive nuclear emulsions N-2, N-3 are about the same as. those of "Ilford C2". Nuclear emulsions for detecting thermal neutrons "N-2 loaded with boron or lithium" seem better than "Ilford C2 loaded with boron or lithium". The sensitivity of electron sensitive emulsion N-4 is of the same order as that of emulsion "никфи P" and "Ilford G5". The hypersensitized electron sensitive emulsion N-5 is also discussed.
