Standardization of P-32 radioactive solution

Caio Pinheiros Marques, Marina Fallone Koskinas, Jamille da Silveira Almeida, Ione Makiko Yamazaki, Mauro da Silva Dias


The standardization solution using three different methods is presented. The disintegration rate was determined by the CIEMAT/NIST and TDCR methods in liquid scintillator systems and self-absorption extrapolation method using 4π(PC)-β system. The results obtained for the activity of the 32P solution were compared and they agree within experimental uncertainties.
