Potential scattering radiation exposure for radiation workers on eye in the cath lab room

Abstract

The scattering radiation of radiation workers especially the eyes on fluoroscopy examination relatively large. Therefore, the potential for receiving radiation exposure for radiation workers needs further evaluation and analysis. This study aims to evaluate the potential of scattering radiation received by radiation workers on the eye. The method was placing the surveyor with a variation of height 150, 160, 170 cm from the floor in a position representing such a doctor (radiation worker) when performing catheter surgery. Irradiation includes 3 modes namely cine, 1-minute, and 4-minutes fluoroscopy. The results of scattering radiation exposure at an altitude of 150 cm at 10-seconds mode cine, 1-minute, and 4-minutes mode fluoroscopy is 6.18-18.96 µSv, 1.10-16.73 µSv, 6.03-15.12 µSv, respectively. The results of scattering radiation exposure at an altitude of 160 cm at 10-seconds mode cine, 1-minute, and 4-minutes mode fluoroscopy is 1.52-69.18 µSv, 2.97-58.49 µSv, 11.23-14.36 µSv, respectively. The results of scattering radiation exposure at an altitude of 170 cm at 10-seconds mode cine, 1-minute, and 4-minutes mode fluoroscopy is 0.91-1.06 µSv, 2.97-58.49 µSv, 7.28-68.14 µSv, respectively. In conclusion, the use of cine mode at 160 cm height from the floor was the best setting for radiation workers (doctors).
