Increasing of registering capacity of nuclear emulsion for autoradiography

The ways of increasing detecting power of the type M nuclear emulsion gel have been investigated in these studies. There have been found conditions under which type M emulsion sensitivity increased by 15 to 20% without increasing fog grain background. The stability of photographic sensitivity during emulsion gel storage increased by two times. The prevention of latent image fading (by means of layer moisture content) decreased to 1.2% and increasing the detecting power of the emulsion (by means of exposure temperature) by up to 370C. The exposure time of tritium labelled autographs has been decreased to about 20%. (author)
