Abstract

Instalasi radiologi merupakan unit pemeriksaan penunjang dalam bidang kedokteran, yang melayani pelayanan diagnosa, perawatan atau rencana perawatan dan evaluasi atau kontrol. Instalasi radiologi memanfaatkan radiasi pengion dan non pengion. Bahaya yang dihadapi dalam instalasi radiologi adalah bahaya radiasi. Data yang digunakan adalah data sekunder dari hasil pemeriksaan kesehatan berkala tahun 2020-2022, yang meliputi data karakteristik demografi dan pemeriksaan laboratorium. Selain itu, hasil pengukuran dosis radiasi diperoleh dari Balai Pengamanan Fasilitas Kesehatan (BPFK) Makassar. Data-data tersebut diolah menggunakan Microsoft Excel. Berdasarkan hasil pemeriksaan kesehatan terhadap petugas radiologi di RSUD Dr. M. M. Dunda, menunjukkan bahwa paparan radiasi berpengaruh terhadap kadar hemoglobin, leukosit, SGPT, dan SGOT. Akan tetapi, hasil pemantauan dosis radiasi dari tahun 2020-2022, menunjukkan bahwa jumlah dosis yang diterima oleh petugas radiologi di RSUD Dr. M. M. Dunda per tahunnya masih berada di bawah batas ambang yang ditentukan oleh BAPETEN, atau masih dalam kategori aman. Rumah sakit wajib melakukan pemeriksaan kesehatan pada para petugas radiologi yang meliputi pemeriksaan fisik, laboratorium, dan pemantauan rutin dosis perorangan, untuk memantau kondisi kesehatan petugas dan memastikan bahwa dalam menjalankan tugasnya, petugas radiologi dalam kondisi sehat.

Abstract

Instalasi radiologi merupakan salah satu unit penunjang medik yang memberikan pelayanan pemeriksaan profesional dengan hasil dalam bentuk gambar atau image untuk membantu para dokter dalam menegakkan diagnosa pasien yang ditangani. Instalasi radiologi memanfaatkan radiasi pengion dan non pengion, yang memiliki potensi bahaya radiasi yang berdampak pada kesehatan pekerja radiasi. Data yang digunakan adalah data sekunder dari hasil pemeriksaan kesehatan berkala tahun 2020-2022, yang meliputi data karakteristik demografi, pemeriksaan laboratorium, dan hasil pengukuran dosis radiasi para pekerja radiasi di RSUD Prof. Dr. dr. Aloei Saboe, yang diperoleh dari Balai Pengamanan Fasilitas Kesehatan (BPFK) Makassar. Data-data tersebut kemudian diolah menggunakan Ms. Excel. Berdasarkan hasil pemeriksaan kesehatan terhadap pekerja radiasi di RSUD Prof. Dr. dr. Aloei Saboe, menunjukkan bahwa paparan radiasi berpengaruh terhadap kadar leukosit dan SGPT. Akan tetapi, hasil pemantauan dosis radiasi dari tahun 2020-2022, menunjukkan bahwa jumlah dosis yang diterima oleh pekerja radiasi di RSUD Prof. Dr. dr. Aloei Saboe per tahunnya masih berada di bawah batas ambang yang ditentukan oleh BAPETEN, atau masih dalam kategori aman.

Abstract

MRI examinations use a radiofrequency pulse (RF), which is absorbed by the body when the electromagnetic field is emitted. This is called the specific absorption rate (SAR) effect, which is defined as the heat absorbed per mass of tissue. The type of research uses a systematic literature review or Literature Review with a qualitative approach, with inclusion criteria for publication journals that discuss the effect of body weight on SAR values ​​and changes in body temperature on MRI, as well as journals using retrospective data as clinical and quasi-experimental studies using patients or phantoms. Data processing is carried out by tabulating journals. Data is analysed descriptively and synthesizing research results, the results of which are reported narratively and are systematic, clear, comprehensive, by identifying, analysing, and evaluating through the collection of existing data with explicit search methods and involving a critical review process in selecting studies by aggregating data based on facts with a medical approach. The ten journals the author used have the same results. The results obtained from journals using variations in body weight that are classified as thin body weight (40-49 Kg) have lower SAR values ​​than patients who are classified as normal weight (50-59 Kg) and patients with fat body weight (60-69 Kg) and patients with Obese weight (70-79 Kg) have SAR values ​​far above the SAR value in patients with normal bodies. This proves that body weight will affect the amount of RF absorbed by the body, causing tissue heating, which causes an increase in SAR values. Weight gain can affect the increase in SAR values ​​because the heavier the object, the greater the amplitude of the RF emitted, causing heating in the tissue, causing the SAR value to increase. An increase in body temperature can affect the increase in SAR values ​​because RF absorption will interact with body water molecules to increase movement, equivalent to a rise in energy that will increase body temperature, due to tissue heating. There is an influence of body weight variation on the SAR value which shows that the amount of body weight determines the amount of RF emitted so that the body will absorb a lot, and there is an influence of body weight variation on the increase in body temperature which shows that if the body has a lot of fat, the fat in the subcutaneous tissue can maintain the temperature, both hot and cold and has an effect on RF radiofrequency exposure which adjusts to the surface of the object.

Abstract

The use of handphone is increasing, making handphone users have to focus more on the side effects of using handphone on health. Handphone is included in the category of electromagnetic waves. Exposure to electromagnetic fields can affect human health, especially the hematological profile. This type of research is observational research with a descriptive approach. Hemoglobin, erythrocyte, leukocyte and thrombocyte levels were obtained from the results of blood checks in the laboratory. The results showed that exposure to handphone radiation caused a decrease in hemoglobin levels up to 11%, an increase in erythrocyte levels up to 13%, an increase in leukocyte levels up to 14%, and an increase in thrombocyte levels up to 35%.Handphone radiation triggersoxidative stress caused by formation of ROS (Reactive Oxygen Species).

Abstract

Matrix Laboratory (MATLAB) is a software based on matrices, which is easy to use for solving various mathematical and computing problems. This study aimed to determine how variations in tube current (mA) affect the radiographic image of the cranium using the MATLAB program and to assess the program's quantification of this effect. The sample in this study consisted of 3 volunteers who performed AP projection cranial radiography examinations with varying tube current at Pelamonia TK. II Hospital, Makassar. Each sample had the same treatment in patient preparation, examination position, examination projection, and the same exposure factor value, which differed only in the use of tube current values, ​​where the volunteer 1 with 200 mA, the volunteer 2 with 250 mA and volunteer 3 with 320 mA. Measurement of the quality of the AP projection cranium image with tube current of 200 mA, the percentage was 96.11%. At 250 mA, the percentage was 95.00%; at 320 mA, it dropped to 92.78%. It was determined that the optimal tube current variation was 200 mA with the highest percentage in measuring the image quality (density, contrast, sharpness, and detail) of the AP projection Cranium against variations in tube current is almost perfect.
