Investigation of Quality Control Measurements with Aging X-Ray Machines

The investigation of Quality Control measurement (QC) with ageing x-ray machines was undertaken. Ten x-ray machines were examined across different hospitals within Makurdi metropolis, Benue State using Gammex 330 kV meter and ten (10) X-ray Machines in government hospitals (GH) and private hospitals (PH) with age’s (4-12) years for new X-ray Machines and (22-47) years for aged X-ray Machines. With these, on the quality of diagnostic X-rays and patient’s dose were examined separately when a graph of age of the machine was plotted against the power n of the kVp and a graph of machines age was plotted against radiation intensity. Based on the analysis obtained in this study, the value of n for the new machines with ages (5-12) years has a value of and aged machines with ages (22-47) years has a value of. This shows that there is a relationship between age and n. In conclusion, the findings of the present study showed that the output radiation dose of new and aged x-ray units differs at the same kVp and mAs measurements, indicating that the x-ray tube deteriorates as its ages increase, thereby posing higher health risk to patients and as such, the study recommends that QC measurement be undertaken on x-ray machines at definite stages of the machines life to verify the effects of aging of a machine on patient's dose.

STUDI TENTANG INTENSITAS SUARA DANUPAYA PENGENDALIAN KEBISINGAN DI BANDAR UDARAHUSEIN SASTRANEGARA BANDUNG TAHUN 2014

PDAM Tirtawening Environmental Quality Control Measurement Laboratory Bandung stated thatHusein Sastranegara airport had highest noise intensity equal to 89.83 dB (A) so that the researcherwants to investigate the sound intensity and noise control in the Husein Sastranegara airport Bandung2014.The research design used was descriptive research which was intended to obtain vivid descriptionrelated sound intensity and noise control in Husein Sastranegara airport Bandung 2014 with five-pointmeasurement that describes the apron (aircraft parking space), check in / luggage space and the ticketprocess, passengers waiting room, public park, and housing.The research results shows that the sound intensity in Husein Sastranegara airport Bandungmeasurement in all locations for 83.78 dB (A) on the apron (aircraft parking area), 72.66 dB (A) at thecheck in / hall ticket and luggage process, 75.37 dB (A) in the passenger waiting room, 65.93 dB (A) atthe public parking lot and 68.52 dB (A) at the housing. The highest sound intensity results was in theapron (aircraft parking area) 85.33 dB (A) at 08:40 am.Manager of Husein Sastranegara airport Bandung expected to encourage the airports employeesto use personal protective equipment such as ear muff while on duty at the apron (aircraft parking) andconduct sound intensity measurement on a regular basis in order to recognize hazard that can interferewith employee activities.
