Investigation of radiological protection status and radiation exposure level at interventional workplace in Zhejiang province / 中华放射医学与防护杂志

ABSTRACT

Objective To explore the current status of radiation protection in interventional procedure and to analyze the existent problems.Methods Using the random sampling,70 interventional radiology workplaces were selected from Hangzhou,Ningbo,Wenzhou,Shaoxing and Jinhua.Information on personal radiation protective products and equipment was collected by filling out the form by hospital and the radiation dose was monitored at various body parts of the workers and at the outside of the operating room.Results All hospitals have been equipped with personal radiation protective products and equipment,22 of which were not with these products and equipment as required.Chest,abdomen and lower limb of interventional radiology workers are easy to receive higher radiation dose than in head (F =4.85,4.92,P ＜ 0.05).The acceptance rates among different body parts of the workers were difference significantly (x2 =35.14,14.92,P ＜ 0.05).Using protective curtain can reduce the radiation dose significantly (t =11.61-68.28,P ＜ 0.05).Meanwhile,it also can improve the acceptance rates significantly (x2 =6.09-28.45,P ＜ 0.05).Conclusions It is necessary to strengthen the use of radiation protection equipment among interventional radiology workers to reduce the levels of the individual doses to them.Hospitals must enhance the routine monitoring for improved radiaton protection.
