Abstract:

Monolayers as radioactive sources have the following outstanding qualities 1 The radioactive atoms are spread completely homogeneously over the emitting surface. 2 The number of active atoms depends only on the area of these layers and on the isotope abundance. 3 Monolayers are weightless sources of zero thickness with insignificant self-absorption. 4 These sources can be made with any desired activity for a number of elements carbon-14, hydrogen-3, phosphorous-32, and others. They are easily reproducible and relatively permanent. Usage of radioactive monolayers as standards in assay work and for dosage determinations by means of G-M counters and radioautography is recommended. Author
