This study aims to analyze the effect of distance and fluoro time on increasing workers radiation dose inside Cath Lab room. Also to analyze the differences results of TLD and Pocket dosimeter in determining workers radiation dose. There are 254 data is needed for statistical analysis, 206 data for analyzing the relation of distance and Fluoro-time against dose, and 276 data from Pocket dosimeter plus 6 data from TLD measurements for analysing the differences of dose on Pocket dosimeters and TLDs. From statistical analysis showed that each exposure factor had no effect on worker dose, but simultaneously exposure factor impacted to dose 14,9 % for Operator and 15,5% for Radiographer . In addition, long-time of fluoro-time does not relate to the dose. The trend shows a decreasing of dose along the Fluoro time axis for both distances. Meanwhile, Radiographer tends to receive dose more stable than Operators due to their distance from exposure area. Moreover, Dose recorded on TLD are consistently higher than on Pocket Dosimeter.
