Abstract

An analysis of radiation dose rate has been conducted by using surveymeter Inspector Sn.46685 in the working area of the Nuclear Medicine installation at Abdoel Wahab Sjahranie Hospital. This study aims to measure the rate of radiation exposure and conduct an evaluation based on the control of the work area. Data collection is carried out in the room in the Nuclear Medicine installation. The measurement results showed that the rate of radiation exposure in the working area of nuclear medicine installations ranged from 0.09-21.56 μSv per hour. The radiation exposure rate obtained is still classified as below 10 μSv/h, but in the waste chamber the measurement obtained is relatively high because it exceeds 10 μSv/h.

Abstract

Dose Calibrator is one of the dosimeters used to measure radionuclide activity before being given to patients. In order to function as a radiation dosimeter, the dose calibrator must have several good dosimeter properties such as precision and stability. To test the dose calibrator, a source used by the hospital is required. One isotope that is widely used in the field of nuclear medicine, namely Tc-99m. The research steps this time are: firstly the elution performed by radiopharmaceuticals, secondly measuring background activity (background), thirdly calling for Tc-99m sources, fourthly measuring Tc-99m activity, fifthly calculating Tc-99m activity for testing precision, and sixth evaluate the results. Based on the research results on the precision test, it was found that the measurement results for the Tc-99m source were obtained at 0.578%. It can be concluded that the Capintec CRC 25R dose calibrator has good characteristics and performance, so that the measurement results can be trusted.

Abstract

The utilization of radiation in the field of nuclear medicine uses several main tools, one of them is the gamma camera. In its use, the gamma camera must always be in prime condition in accordance with the regulation of the Badan Pengawas Tenaga Nuklir (BAPETEN) No. 17 of 2012. To ensure that the gamma camera is always in prime condition, it is necessary to carry out several QCs (Quality Control) within a certain period of time with reference to international standards and recommendations from manufacturers. QC results show the measured value still within the required range (acceptance criteria), so it can be said that the gamma camera is in prime condition and ready to be used. The Nuclear Medicine Installation of RSUD A. W Sjahranie Samarinda use Cobalt-57 flood source plates to measure extrinsic uniformity during daily QC. This study used data in the form of tables of extrinsic calibration measurements and verification measurements as well as graphs of Cobalt-57 activity against QC time with extrinsic calibration methods and verification measurements were shown in this study. The conclusion is the lower the activity, the longer the QC times. Besides, the QC times based on the extrinsic callibration and verification measurements are not much different.
