Abstract: In order to solve the measurement difficulty of 18F activity, a new method (attenuation method) for measuring 18F activity with energy spectrum is put forward based on the decay law and binding energy spectrum multi-time span detection. Based on empirical calculations, the relative uncertainty of attenuation method is 3.1%. It is preliminarily believed that this method is correct and feasible, and can solve the technical difficulties in energy spectrum measurement of 18F.

Key words: positron decay, γ spectrum, activity measurement, 18F
