The experimental technique based on scanning of positron implantation profile, hereafter referred to as the DSIP is used for the determination of linear absorption coefficient for positrons emitted from a 48V source into water. This coefficient is equal to 1/(299±62) µm–1. The determined value is in agreement with the one obtained from the computer simulations using the well known EGS nrc 4.0 and GEANT4 codes. The experimental technique was used for the determination of linear absorption coefficients for 48V positrons in materials of biological origin. The presented data can be useful for PET studies because of similarities of the 18F and 48V positron implantation profiles.
