Background : There are three ways to protect yourself from the danger of radiation, namely by regulating the length of irradiation (the effect of time), the use of anti-radiation material (shielding), and adjusting the distance from the radiation source (distance). In order to be safe in carrying out x-ray irradiation, patients and operators must take three steps so that radiation hazards can be minimized (Nunung, 2004). One way to check the danger of external radiation is to use a radiation barrier. This method is generally preferred, because it creates safe working conditions. Besides that the time and distance factors can be monitored continuously at the time of work, so that radiation workers can be guaranteed safety.Methods: This research is quantitative research with an experimental approach. The method of data collection in this study is observation, direct experiments and documentation. The types of sand to be used in this study are south beach sand, opaque sand, progo sand, white mountain sand and volcanic sand.Result : Concrete using sand material from South Beach has the lowest HVL value of 0.8644cm. Conclusion :The HVL value possessed by concrete with South Beach sand material is most effective in resisting x-ray radiation.

The method used in the research was quantitative that was experimenting on water (H2O), which was subjected to x-ray radiation with tube voltage variation and calculating the level of peroxide (H2O2) in water that has been exposed to radiation. The study was conducted by irradiating one liter of water added with five milliliters of KMnO4 and one milliliter of H2SO4 as a catalyst with tube voltage variation of 40 kV, 60 kV and 80 kV with 200 mSec and 400 mA of 10 irradiation times. The analysis was performed using a spectrometer. The results find that the more radiation, the higher the free radicals are formed. While the higher the x-ray energy, the fewer free radicals are formed.

The radiographic examination technique of the Thoracolumbar Vertebrae with scoliosis cases consists of right and left bending Anterior posterior (AP), Lateral, and Anterior Posterior (AP) projections, as well as the addition of the Ferguson method and fulcrum projection. The procedure for scoliosis examination at radiology installation in RSUD (Regional Hospital) Karanganyar is unknown, so it is necessary to do research to find out the examination procedure and the effectiveness of using these projections. This study aims to determine the procedure for radiographic examination of thoracolumbar vertebrae with clinical scoliosis at the Radiology Installation of RSUD Karanganyar. This research is qualitative research with a case study approach. The data collection method included observing scoliosis examination which included preparation of tools and materials, patient preparation, and examination techniques, then reinforced by interviews with radiographers and doctors to find out the procedures and reasons for using these projections. The results of observations and interviews were analyzed by means of data reduction, data presentation, then conclusions were drawn. The results of the study showed that the thoracolumbar vertebrae examination procedure with clinical scoliosis in Radiology Installation of RSUD Karanganyar used the AP and Lateral projection technique. The reason for using AP and Lateral projections was because these projections served as initial screening for scoliosis patients and could already establish a diagnosis. Both projections provided a smaller dose of radiation received by the patient and were in accordance with the request of the sending doctor. It is advisable for further examination of the thoracolumbar vertebrae with clinical scoliosis add the right and left bending projections and Ferguson, because it aims to provide information that cannot be seen from the AP and lateral projections.

The study was conducted at RSPAD Gatoet Soebroto with activity measurement method using dose calibrator and counting gamma cameras with ROI (region of interest) technique in the total thyroid area and outside the thyroid gland called background. With sample of 30 people, the age range is 25-60 years with clinical hyperthyroidism. The thyroid gland is performed by injecting Tc-99m pertechnetate as much as 3-5 mCi intravenously, then imaging the thyroid gland for 10-15 minutes after injection using a dual headspect gamma camera. The purpose of this study was to determine the effect of position change, background ROI distance and radioisotope biodistribution on the Tc-99m pertechnetate uptake value on thyroid scan examination. The results showed the percentage of thyroid uptake at distance of 2 cm various background positions obtained mean 24.106 ± 3.476%, at distance of 4 cm various background positions were obtained averaging 24,107 ± 3,476% and at distance of 6 cm various background positions obtained a mean of 24,108 ± 3,476%. While biodistribution showed in the area of the thyroid gland and surrounding salivary glands in hyperthyroid disease, the mean value of the thyroid gland was 562293.167 ± 122587,58 count, the pharynx was obtained at an average of 23344,36 ± 13573,35 count, on the right mandible was obtained at 8745,66 ± 4200,01 count, and the left mandible obtained a mean of 9610.66 ± 4479.10 count. The relationship between percentage of thyroid uptake in the background of 2 cm and thyroid hormone levels is shown in the equation line Y (T3) = - 0.1586X + 6.3315 (r = - 0.5378 where the relationship is strong and meaningful p = 0.0580), Y (FT4) = 0, 9374X - 16,738 (r=0.5118 strong relationship, and means p = 0.0738), and Y (TSH) = 0.1775X - 2.2629 (r = 0.1715 weak relationship and not meaningful p = 0.5754). In conclusion there is a strong relationship between the percentage of uptake with thyroid hormone T3 and FT4, on the contrary a weak relationship with TSH hormone.
