Abstract:
The decreased occupational dose limit for eye lens has lead to an extensive focus on the eye lens dose monitoring and protection for occupational staff in interventional procedures.Based on the literature investigation of existing measurement and calculation results,the efficiency and influence factors of eye lens protective equipments for interventional staff are analyzed,and the suggestions for selection and use of them are provided.The main contribution to the eye lens dose to interventional staff is unshielded radiation which reaches the eyes directly.The key factors to inflence the efficiency of eye lens protective equipment is the geometric conditions such as structure,beam projection,position arrangement and operator postures,instead of lead equivalent thickness.Equipment of 0.5 mm lead equivalent thickness is enough to protect the eye lens of interventional staff.The combination of lead glasses and lead barrier can provide better protection in clinical practice.
