[en] A wide variety of consumer products that contain radionuclides are available to the general public. Estimation of radiation doses to man from exposures to these products requires that the entire life span of each product be defined in a manner that identifies persons who may be exposed and quantifies the conditions under which exposures may occur. This paper presents models of steps which make up the paths for transportation and distribution of consumer products. Fire probabilities and damage rates to parcels during transportation are included. Transportation steps considered include those used to move parcels via truck, air, first-class mail, and parcel delivery. Distribution steps include handling in distribution centers, warehouses, and retail stores. A hypothetical distribution scheme is presented to illustrate application of the exposure scenarios described in model
