Abstract

Abstract: The radioactive pollution of iron ore imported via Beilun Port was studied by measuring the imported iron ore deposited at Beilun Port.The result indicates that the average annual effective dose equivalent of γ irradiation is 0.15 mSv/a for the nearby residents of the imported iron ore yard and 0.21 mSv/a to the workers involved, which both are below the national standard for building materials.Its radon pollution is low, near to the environment background value.

Key words: Imported iron ore, Radioactivity, Measurement, Dose estimation
