Abstract

This research aimed at finding out the effect of the patient's age on the absorbed dose obtained during the thorax examination. The observation data used is the exposure factor in the form of the tube voltage (kV), tube current (mA), irradiation time (s), and focus film distance (cm). The age range used is grouped based on the elderly age category established by the Ministry of Health of the Republic of Indonesia which ranges from 46 years until 85 years of age. From the data on the exposure factor and age of elderly patients, the oneway ANOVA statistical test was conducted. From the results of these statistical tests, the results obtained FCalculate value is 0,201 and sig 0,821 for Thorax AP examination and the results obtained FCalculate value is 0,790 and sig 0,476 for Thorax PA examination with the FTable value is 3,81 and the sig is 0,05. Therefore, based on the testing criteria in statistics of the initial hypothesis (H0) is accepted or it can be concluded that age does not affect the amount of X-ray radiation absorbed dose received by elderly patients in thorax examinations from the age range of 46 years until 85 years.

Abstract

Dose calibrator is a measuring tool that is widely used in hospitals to determine radionuclide activity in nuclear medicine services. In determining this activity it has several factors; namely precision, accuracy and stability which is become depining factor of the tool suitability. The aim of this research is to determine the level of precision, accuracy and stability of the Capintec dose calibrator type CRC-25R with an I-131 source and a standar Cs-137 source at the Nuklear Medicine Installation of RSUD A.W. Sjahranie Hospital Samarinda. Data processing in this research was carried out using quantitative analysis tecnhniques, namely descriptive statistics. This analysis technique use primary data obtained from direct measurements of radionuclide activity. Data processing was carried out by measuring radionuclide activity, namely source I-131 and standard source Cs-137 of 0,1 ml using a Capintec type CRC-25R for 7 days. These results are visualized in the form of tables and graphs of precision, accuracy and stability tests from both source with predetermined limits. Base on this research, it can be concluded that if we look at the precision, accuracy, and stability test using I-131 source anda Cs-137 standard source on the Capintec type CRC-25R at A. W. Sjahranie Samarinda Hospital, it can be used to measure a constant source over a long periode of Long time.
