Objectives: The significant rise in modern cath lab units has led to a proportionate increase in cath lab procedures and subsequent radiation environment may elevate the occupational radiation exposure to staff. This study aimed to assess the collective impact of fundamental radiation safety devices in the cath lab on decreasing occupational radiation exposure to staff. Methods: This study was conducted in our cath lab room, equipped with a Siemens Artis cath lab unit. Measurements were performed using RaySafe X2 detectors and Thermo Luminescent Dosimeters (TLDs). Dose assessments were conducted without safety measures and then found a considerable reduction of dose by adding basic radiation safety measures. Findings: The use of lead aprons resulted in a substantial reduction( 92%) in radiation dose. The effect of time and distance versus dose was plotted. The impact of lead flaps and the use of a ceiling suspension shield quantify reductions in scattered doses. The cumulative impact of each safety measure was calculated, and the outcome indicates a 99% reduction in dose. The importance of utilizing all available protective measures when working with radiation cannot be overstated. It is essential for maximizing safety, minimizing risks, and fostering a culture of safety within radiation environments like cath labs. Novelty: This is a thorough assessment of different radiation protection strategies in the specific setting of a Cath lab. It not only evaluates individual measures but also considers their combined impact and the calculation based on the exit dose from the patient.
