Abstract

Research has been done to identify radioactive elements and determine  Work Level Month (WLM) values on workers in the sized room of 2m x 2m using gypsum material. Identification of radioactive elements in gipsum samples using Laser Induced Breakdown Spectroscopy (LIBS) methods and measurement of radiation dose in gypsum walls using surveymeter methods. Identification of radioactive elements to the LIBS method showed an element of Th, U, K were detected. The accumulated dose of radiation detected in the room using gypsum walls is (1,6993±0,0169) μSv and the accumulated dose of radiation detected in the room without gypsum walls is (0,5657±0,0292) μSv. WLM values from the room use a gypsum walls if workers work for 1 years is 0,9924 WLM, then it is still considered safe because it is still below the RR values that has been determined that is equal to 50 WLM.

Abstract

CT Scan for head data for children have been processed by using a software name IndoseCT. CT Scan usually use for diagnose part of human body, but CT Scan for head is the most. Data processing was carried out with the IndoseCT software to obtain effective dose values. The highest effective dose value with contrast and non contrast received by 1 until 5 years old patients. Examination with contrast has an effective dose value of 1.29 mSv and for non contrast examination has an effective dose value od 1.16 mSv, meanwhile the lowest effective dose for examination with contrast received by 0 until 1 years old patients with value of 0.94 mSv and for non contrast examination of 0.9 mSv received by 16 until 18 years old patient.
