Determination of Eye Lens Dose, Hp(3) Using TLD-700H at PTKMR-BATAN

The use of ionizing radiation in medical institutions is increasing year by year. But the negative impact of radiation on the eye lens is increased, especially in interventional radiology, reported by Chodick et al, 2008 and Vano et al, 2010. "Lens of the Eye Dosimetry has become increasingly important with the changes recommended by ICRP 103/2007 (Statement on Tissue Reaction). The ICRP issued new recommended limits for radiation dose to the lens of the eye, Hp(3) due to concerns over cataracts in April 2011. This reduction of annual dose limits to the lens of the eye from 150 to 20 mSv (2 rem) has created the need for enhanced monitoring using dosimetry as close as possible to the eye. In Indonesia, based on the Government Regulation of the Republic of Indonesia No.63/2000 concerning Safety & Health of Ionizing Radiation, ''In every utilization of ionizing radiation, the safety factor of the workers must be given on the highest priority''. Acceptance of radiation doses by radiation workers must kept as low as possible so as not to exceed the dose limit value permitted by the Supervisory Board and based on the Government Regulation of the Republic of Indonesia No. 33/ 2007 concerning Safety of Ionizing Radiation and Radioactive Source Security, ''Safety measures are needed to protect workers, community members and the environment from radiation hazards''.
