Background/Aims : The increasing use of diagnostic and therapeutic interventional radiology calls for greater consideration of radiation exposure risk to radiologist and radiological technician, and emphasizes the proper system of radiation protection. This study was designed to assess the effect of a protective grass shield.Methods : A protective grass was following data depth, 0.8 cm; width, 100 cm; length, 100 cm, lead equivalent, 1.6 mmPb. The protective shield was located between the patient and the radiologist. Thirty patients (13 male and 17 female) undergoing interventional radiology between September 2010 and December 2010 were selected for this study. The dose of radiation exposure was recorded with or without the protective grass shield at the level of the head, chest, and pelvis. The measurement was made at 50 cm and 150 cm from the radiation source.Results : The mean patient age was 69 years. The mean patient height and weight was 159.7 ± 6.7 cm and 60.3 ± 5.9 kg, respectively. The mean body mass index (BMI) was 20.5 ± 3.0 kg/m2. radiologists received 1530.2 ± 550.0 mR/hr without the protective lead shield. At the same distance, radiation exposure was significantly reduced to 50.3±85.2 mR/hr with the protective lead shield (p-value＜0.0001). The radiation exposure to radiologist and radiological technician was significantly reduced by the use of a protective lead shield (p value ＜0.0001). The amount of radiation exposure during interventional radiology was related to the patient' BMI (r=0.749, p=0.001).Conclusions : This protective shield grass is effective in protecting radiologist and radiological technician from radiation exposure.
