SUMMARY Suppression of background in autoradiographic materials can be influenced by control in manufacture, transport and storage, and user handling. Fogging by radiation during transport and storage is a definite risk, but for some materials can be combated by latent‐image fading during storage before transfer to the specimen. Leaching out of emulsion constituents during transfer enhances the risk of background growth, and can be counteracted by transferring from a suitable solution. Background growth is positively promoted by chemographic agents derived from wood and other materials. The transfer solution helps to block chemographic action, as does storage of the transferred emulsion at a low temperature or in a non‐porous and photographically inert container.
