Abstract. Early detection of breast cancer is the first step in prevention that can be done by women, therefore when one is diagnosed with breast cancer, the appropriate treatment can be performed quickly and accurately. Early diagnosis of breast cancer can be a way of mitigation in preventing breast cancer through the use of mammography. Bureau of Radiology as said by The Joint Commission on Accreditation of Hospitals (JHCA) stated that one of the responsibilities of the radiology unit is to control the quality of service which aims to minimize the radiographic image repetition factor; as well as maximizes the quality of radiographic image. Quality control tests are an effort that is needed on the mammography X-ray diagnostics tools. This is done to maintain the quality of expected output. The parameters that are included within the radiation output are the magnitude of current and the voltage of tube that are produced; therefore they remained constant and correspond to the recommended standard. Bureau of Radiological Health, as said by JHCA mentioned that to control the quality of image which will minimize the radiographic image repetition and maximizes the quality of radiographic image. Therefore the radiation output will not be dangerous later. The early stage of the quality control test on the machine was conducted by setting all the filtrations which were placed to capture the x-ray on the x-ray plane tube with minimum value. Then, ionization chamber is placed on the test subject points; right after that the distance between it to the radiation source is noted. The x-ray film is place on a film on the compression table of the patient and the distance between film and the focus point is noted. This is then exposed using a target filter Mo/Mo by setting the current as well as variation the voltage and time. The standard voltage measurements are 20-33kVp. This data is from the observations of time exposure; the output value is then noted. The above procedure is conducted from the minimum voltage to the maximum voltage. The output ray is measured for each voltage. The same procedure is conducted to the target filter Mo/RH. The results obtained are that the greater the input voltage and current will subsequently produce greater doses, therefore the exposure has exceeded the standard limit 0.1 mHy with longer exposure time. The HVL density thickness on the mammography X-ray machine determined the quality of the beam and the doses of x-ray exposure on the mammography machine. The output stability of x-ray beam exposure in the mammography machine mode Mo/Mo still fulfill the standard which is the value of 69% Keywords: Quality Control, Sinar-X, mammography, Mp/Mo, Mo/RH

Currently, several regional general hospitals in Banda Aceh now have excellent support facilities, one of which is a diagnostic X-ray machine. The performance of diagnostic X-ray machine should be checked to determine if the dose received does not harm a patient and produce a good image and provide diagnostic information in a timely and accurate, therefore there are necessary for quality control activities on the machine X-ray. Factors that affect the dosing and imaging results, among others, the amount of the provision of current and voltage. From the research shows that the value of the output voltage generated is not much different from the value of the input voltage with a percentage value below 5%. This value shows a good output machineX-ray because it is still under the maximum tolerance limit of 10%. So the overall results of observations on the machineX-ray is in hospital, the quality control measurements gave values still within safe limits. Then by giving a higher input voltage turns also affect the amount of energy produced, thus affecting also absorbed dose X-rays are produced.

Abstract. Determination of radon concentrations in dwelling in Aceh region by using a passive method has been conducted. In this research, area considered was divided into several sections called grid. Each grid represents an area of 60 km x 60 km in which, depend on public response, 6-10 passive radon monitors were installed. The number of passive radon monitors installed in Aceh is 200 units, and they can be taken back as many as 191 units or 95.50 %. The passive radon monitors have stayed in dwelling for 3-4 months and after period of the exposure, those radon monitors were taken back and brought to laboratory for further process, and then the track were read and the radon concentrations were calculated. Furthermore, data of radon concentration in dwelling and GPS location were put into MapInfo Software v.10.5 to create a map of radon concentration. The results of the analysis of the radon concentration in dwelling in Aceh demonstrate that the concentrations are in the range of 3.32 ± 0.23 Bq/m3 up to 68.30 ± 4.83 Bq/m3. This result was lower than the radon reference level determined by UNSCEAR, which was 300 Bq/m3. The data are useful in the regional extension and development plans, as well as the basis for health policy analysis due to the existence of radon in Indonesia. Furthermore, these data will become the contribution of Indonesia in the international world through UNSCEAR, IAEA and WHO. The data obtained can be used as partial data in creating a map of radon concentration in residents’ houses in Aceh, as a part of the map of radon concentration in Indonesia.
