A cheap, calibrated photographic method for the screening of X-ray film autoradiographs

This report describes the use of a calibrated photographic method for the screening of X-ray film autoradiographs. In the method the autoradiographic film is contact printed onto photographic film of high contrast, and the latter is contact printed onto photographic paper of suitable contrast. Special features of e.g. deoxyglucose-autoradiographs are thus visualized. The method is inexpensive, and it can be used as a complement to densitometric point measurements of X-ray film autoradiographs.
