The use of electron beam technology has enabled the production of heat resistant pipe for hot water circulation. One of the difficulties in their radiation of pipe products is the uneven penetration of electrons. Quality of the radiation process depends on radiation dose and homogeneity of the dose distribution, Which becomes a major concern when treatments of circular objects like pipes are performed. One method to achieve uniformity in the absorbed dose in the product is to use multi-sided irradiation. The paper discusses the importance of dosimetry mapping in industrial electron beam radiation processing and outlines the challenges in delivering a uniform dose to cylindrical objects. In this study, HDPE pipe of 5mm  Thickness of homogeneous material (40mm outer diameter and 30mm inner diameter) has been chosen For multi-sided irradiation under 2MeV scanned electron beam from the ILU-6 accelerator.
