We monitored the amount of radiation received by surgeons and assistants during surgery carried out with fluoroscopic assistance. The radiation was monitored with the use of MYDOSE MINIX PDM107 made by Aloka Co.
Over a one year period from 20, 8, 1992 to 19, 8, 1993, a study was undertaken to evaluate exposure of the groin level to radiation with or without use of the lead apron during 106 operation. (Group-1)
In another group radiation was monitored at the breast and groin level outside of the lead apron during 39 operations. (Group-2)
In Group-1 the average exposure per person during one year was 46.0μSV and the average exposure for each procedure was 1.68μSV.
The use of the lead apron affirmed its protective value; the average radiation dose at the groin level out-side of the apron was 9.11μSV, the measured dose beneath the apron 0.61μSV. The average dose of exposure to the head, breast at groin level outside of the lead apron, were 7.68μSV, 16.24μSV, 32.04μSV respectively.
This study and review of the literature indicate that the total amount of radiation exposure during surgery done with fluoroscopic control remains well within maximum exposure limits.
