The objective of this paper is experimental studies of the linear absorption coefficient, or mean penetration depth of positrons emitted from ^{22}Na isotope in different materials. For this purpose we constructed a new experimental setup which allows us to scan the depth implantation profile of positrons. For the studied metals: Mg, Al, the obtained values of mean penetration depth coincide well with those which can be calculated using the mathematical formula commonly used but for Si and S the discrepancy has been observed similarly like for polymers.
