Abstract: Through a comprehensive literature investigation, combined with studying the contents of the current relevant standards, this paper investigates the phantom, conversion coefficients and lens dosemeter used in the measurement process. The cylindrical phantom has been used as a phantom for eye lens dose equivalent Hp(3) dosemeter calibration. The dose equivalent conversion coefficient is mainly calculated based on the Monte Carlo method and empirical formula. The Hp(3) measurement methods are various, mainly based on thermoluminescence dosimetry system. The EU has organized three relevant inter-comparisons. The comparison result of irradiation in photon field was better than the result of irradiation in β field. However, due to the application of lead glasses and lead masks, and the division of the sensitive area of the lens, there are still problems to be solved in the measurement and transmission of Hp(3).

Key words: eye lens dose, dose measurement, Hp(3)
