Abstract

Screening is ordinary process airport passanger was machine baggage. X-ray radiation gives impact to eye because eye sensitive of radiation. Many kinds of eye strain symptom got by screening worker such eye poignant. It is neressary to give intervention to decrease the radiation exposure and eye strain for worker by increasing lead shielding on the fluoroscopy machine baggage and setting of worker distance toward the source of radiation. Experimental research with pre-post test control group design. A sampel of 30 people were taken with a simple randomized method which was subdivided into group 1 as a control group without the additional treatment of lead shielding and working distance regulation of the radiation source, group 2 with the addition of a shielding and setting distance as far as 2 m. the study was conducted in August 2017. The variables evaluated were exposure to the received radiation of workes and the strain of the workers eyes. The result of the research is a combination of lead shielding on machine baggage fluoroscopy and setting of working distance to X ray source at X International Ariport significantly (p<0,05) in decreasing radiation exposure received by worker equal to 74,59% and worker eye strain 68,85% for a distance of 1,5 m and decreased radiation exposure to the workers as much as 93, 69% and the eye strain on the worker 89,79% at a distance of 2 m from the radiation source. Concluded that the combination of increasing lead shielding and the setting of worker distance toward the source of radiation decrease thr radiation exposure and eye strain on the screening worker at X International airport.

Abstract

It has been conducted research to determine the effect of X-ray tube voltage variation (kV) on Signal to Noise Ratio (SNR) values by applying the Anode Heel Effect using stepwedge with the addition of 1.5 mm thickness each step. The stepwedge used was 1.5-31.5 mm. The X-ray tube voltage variations used were 40, 50, 60, 70, 80, and 90 kV. Analysis of the effect of X-ray tube voltage variation on SNR values is determined using IMB SPSS Statistics 26 with a simple regression test. The test results showed that variations in X-ray tube voltage affect SNR values, where the greater the variation in X-ray tube voltage then the SNR value would get smaller. The optimal SNR value of 72.685 was obtained at a tube tension of 40 kV and a stepwedge thickness of 27.0 mm.
