Introduction}]{I. Introduction}\par omputed tomography (CT) system consists of an X-ray source? a rotary table, which creates cross section images by projecting a beam of emitted photons through one plane of an object from defined angle positions performing one revolution. \hyperref[b0]{(1)} The radiation dose in X-ray CT has become a topic of high interest due to the increasing number of CT examinations performed worldwide. \hyperref[b1]{(2)} When Godfrey Hounsfield developed the first clinical CT scanner in 1969, a new time of crosssectional imaging of the human body was initiated. The use of CT examinations has increased rapidly since then. Recent surveys in large medical centers have found that CT studies now often account for 25\% of all examinations and 60 to 70\% of the patient dose received from diagnostic radiology. In addition, patient surveys reveal a wide range of patient doses for the same examination. Also, there is now widespread concern about the increase in CT doses. Several different factors contribute to the trend of increasing use of CT scanning and is being documented by international organizations. \hyperref[b2]{(3,}\hyperref[b3]{4)} Subject in this study is 36 points (Figure 1)which scattered around CT machine in CT department were it divided into 3 groups: group (I); which represent the radiation dose rate in workplace area and it include ten points (thirty different CT scans), group (II) which Represent the dose rate inside CT room and it include fifteen points (forty five different CT scans), group (III); which represent the radiation dose rate outside the CT room and it include eleven points (thirty three different CT scans), therefore the radiation dose were measured in three groups through one hundred and eight CT scans. A cross-sectional design to determine the radiation dose that maybe exposed to the medical staff who is working in CT department by measured the radiation dose rate. Statistical analysis was performed by using one way ANOVA test and post hoc test of LSD, HSD. RAM ION meter was used to detect the radiation dose rate. and 18 scanners per million citizens respectively. Although typical CT radiation doses have not significantly changed over the years, usage of CT as a diagnostic tool has dramatically increased. \hyperref[b4]{(5)} The CT scanning has been recognized as a high radiation dose modality, when compared to other diagnostic X-ray techniques, since its launch into clinical practice more than 30 years ago. \hyperref[b5]{(6)} The regulatory bodies lay down norms for protection against radiation and also recommend the dose limits for radiation workers and the general public. The ICRP or the International Commission for Radiation Protection is the international regulatory body. Each country has its national counterpart of the ICRP. \hyperref[b6]{(7,}\hyperref[b7]{8)} The importance of radiation dose from x-ray CT has been underscored recently by the attention given in the scientific literature to issues of dose and the associated risk. The dose levels imparted in CT exceed those from conventional radiography and fluoroscopy and the use of CT continues to grow, often by 10\% to 15\% per year. According to 2006 data, approximately 62 million CT examinations were performed in hospitals and outpatient imaging facilities in the United States (American Association of Physicists in Medicine. ( {\ref 9}) \section[{II. Material and Methods}]{II. Material and Methods}\par This study is a cross-sectional design to determine the radiation dose that maybe exposed to the \section[{III. Result}]{III. Result}\par The data of this research was obtained from Dr. Sardjito General Hospital of Yogyakarta, Indonesia. A radiation dose rate (DR) of 36 points were measured in the CT scan Department through one hundred and eight CT scans for different examinations (brain, chest, and abdomen); the different points scattered around the CT Machine in different position.\par The different of dose rate (mSv/h) value was obtained according to the CT scan type as well as the distance between CT machine and the interest area where the points were measured as shown in (Table \hyperref[tab_0]{1}). The data was collected at the same level of iso-center of CT Machine which equals 103 centimeter from the floor level, therefore all the points (108) in three groups of this research was measured at the same level, after applying one way ANOVA test (P ? 0.05), thus conclude that there are a difference between the points (the dose rate (mSv/h) value in thirty six dose rate points around the CT machine.\par And also to detect if there are a different between the three groups where the dose rate was measured (Table \hyperref[tab_1]{2}), it is done by applying one way ANOVA test (p ? 0.05),thus conclude that there are a difference between the three groups (the mean of dose rate (mSv/h) between three groups in CT scan department). \section[{a) The Three Groups in CT Scans Department}]{a) The Three Groups in CT Scans Department}\par This study divided the CT scan department to the three groups (group I; workplace area, group II; inside CT room area , group III; outside area) each one hasa number of points(Figure 1) where the dose rate was obtained, the result of dose rate will describe to show the dose rate in each point of all groups. Group (I): this group represent the radiation dose rate in workplace area, which include ten points (thirty different CT scans) with the mean dose is (0.0049 mSv/h) and standard deviation (0.00485) as shown in (Figure 2). \section[{Volume XVI Issue II Version I}]{Volume XVI Issue II Version I} \section[{Group (II):}]{Group (II):}\par This group represents the dose rate inside CT room, which includes fifteen points (forty five different CT scans) with mean (10.7451 mSv/h) and standard deviation (12.87781) as shown in (Figure 3). \section[{Group (III):}]{Group (III):}\par This group represent the radiation dose rate outside the CT room, which include eleven points (thirty three thirty different CT scans) with mean (0.008 mSv/h) and standard deviation ( 0.00185) as shown in (Figure 4). \section[{IV. Discussion}]{IV. Discussion}\par In this study, the measurement of dose rate that reach to medical staff workplace at Dr. Sardjito General Hospital, Yogyakarta, Indonesia from CT scans exposure in different points was done, and compare the average of dose rate in each point with ICRP recommendations to ensure that the workplace is safe for medical staff, as well to measure the dose rate that reach to medical staff workplace at Dr. Sardjito General Hospital, Yogyakarta, Indonesia from CT scans exposure in different points, and compare the average of dose rate in each point with the average of dose rate in other points (inside, outside) CT room to define the safest area from CT radiation dose.\par During the CT scan operation there are an X ray production and the x-ray beam passes through the human body, three possible fates await each photon; it can penetrate, it can interact with the human body and be completely absorbed, it can interact and be scattered (secondary radiation) or deflected from its original direction and deposit part of its energy, after all this study was measured the dose rate of scatter radiation during CT examination, in this study there are three groups it will be discussed. \section[{Group (I):}]{Group (I):}\par This group represented the core of this study because the result from this group can answer the research question that; does the quantity of radiation from CT examinations that reach to medical staff workplace at Dr. Sardjito General Hospital, Yogyakarta, Indonesia is less than ICRP recommendations?, as well the result from this group can prove the research hypothesis. The Commission recommends a limit on effective dose of 20 mSv per year averaged over 5 years (100 mSv in 5 years), with the further provision that the effective dose should not exceed 50 mSv in any single year. The 5-year averaging period is intended to provide more flexibility than would be the case with a strict annual limit, while still meeting the Commission's objective that the total effective dose received in a full working life should not exceed about 1 Sv received moderately uniformly year by year. \hyperref[b9]{(10)} In CT scan department the medical staff work eight hours per day, five days per week, forty week per one year so the total work hours of medical staff in Dr. Sardjito General Hospital, CT scan department is two thousand hours. Therefore 20 mSv/h divided by (2000 h) the result will be (0.01mSv/h) or in another way its equal (10µSv/h). The group (I) has a ten different dose rate values points fluctuated from (0 µSv/h) in point number one the safest area in medical staff workplace to the 0.007mSv/h (4µSv/h) in point number fourteen, the most commonly used place from medical staff in points eight, fourteen, and twenty, the mean of this three points is 0.0053 mSv/h (5.3 µSv/h) which mean less than ICRP recommended level and its safe for medical staff that work in this three points, anyway the mean of dose rate in group I area is 0.0049 mSv/h (3.6 µSv/h) which mean the dose rate value in group I medical staff workplace is less than ICRP recommended level (3.6 µSv/h ? 10 µSv/h), thereforethe group (I) medical staff workplace in CT department is safe. \section[{Group (II):}]{Group (II):}\par The measurement of radiation dose rate in this group to compare the average of radiation dose rate in each point with the averageof dose rate in other points inside CT room to define the safest area from CT radiation dose, this objective is very important to the patient companion to find less harmful area inside CT room by receiving as low as of radiation dose from CT machine during CT scan, The group (II) have a fifteen \begin{figure}[htbp] \noindent\textbf{}\includegraphics[]{image-2.png} \caption{\label{fig_0}}\end{figure} \begin{figure}[htbp] \noindent\textbf{1} \par \begin{longtable}{P{0.0625\textwidth}P{0.034999999999999996\textwidth}P{0.22999999999999998\textwidth}P{0.25875\textwidth}P{0.26375\textwidth}} Point\tabcellsep n\tabcellsep Mean of dose rate\tabcellsep Standard deviation\tabcellsep Standard error of mean\\ 1\tabcellsep 3\tabcellsep 0.0000\tabcellsep 0.00000\tabcellsep 0.00000\\ 2\tabcellsep 3\tabcellsep 0.0043\tabcellsep 0.00404\tabcellsep 0.00233\\ 3\tabcellsep 3\tabcellsep 0.1277\tabcellsep 0.09579\tabcellsep 0.05531\\ 4\tabcellsep 3\tabcellsep 37.7333\tabcellsep 1.16762\tabcellsep 0.67412\\ 5\tabcellsep 3\tabcellsep 16.5000\tabcellsep 3.06431\tabcellsep 1.76918\\ 6\tabcellsep 3\tabcellsep 0.0003\tabcellsep 0.00058\tabcellsep 0.00033\\ 7\tabcellsep 3\tabcellsep 0.0020\tabcellsep 0.00000\tabcellsep 0.00000\\ 8\tabcellsep 3\tabcellsep 0.0050\tabcellsep 0.00265\tabcellsep 0.00153\\ 9\tabcellsep 3\tabcellsep 14.8333\tabcellsep 2.11975\tabcellsep 1.22384\\ 10\tabcellsep 3\tabcellsep 42.8333\tabcellsep 1.06927\tabcellsep 0.61734\\ 11\tabcellsep 3\tabcellsep 8.7333\tabcellsep 3.20208\tabcellsep 1.84872\\ 12\tabcellsep 3\tabcellsep 0.0000\tabcellsep 0.00000\tabcellsep 0.00000\\ 13\tabcellsep 3\tabcellsep 0.0020\tabcellsep 0.00000\tabcellsep 0.00000\\ 14\tabcellsep 3\tabcellsep 0.0070\tabcellsep 0.00265\tabcellsep 0.00153\\ 15\tabcellsep 3\tabcellsep 6.8667\tabcellsep 2.56580\tabcellsep 1.48137\\ 16\tabcellsep 3\tabcellsep 12.6333\tabcellsep 6.22923\tabcellsep 3.59645\\ 17\tabcellsep 3\tabcellsep 2.6000\tabcellsep 1.45258\tabcellsep 0.83865\\ 18\tabcellsep 3\tabcellsep 0.0000\tabcellsep 0.00000\tabcellsep 0.00000\\ 19\tabcellsep 3\tabcellsep 0.0043\tabcellsep 0.00058\tabcellsep 0.00033\\ 20\tabcellsep 3\tabcellsep 0.0047\tabcellsep 0.00208\tabcellsep 0.00120\\ 21\tabcellsep 3\tabcellsep 1.0660\tabcellsep 0.30638\tabcellsep 0.17689\\ 22\tabcellsep 3\tabcellsep 4.3667\tabcellsep 2.21209\tabcellsep 1.27715\\ 23\tabcellsep 3\tabcellsep 4.8000\tabcellsep 0.26458\tabcellsep 0.15275\\ 24\tabcellsep 3\tabcellsep 0.0000\tabcellsep 0.00000\tabcellsep 0.00000\\ 25\tabcellsep 3\tabcellsep 0.0023\tabcellsep 0.00058\tabcellsep 0.00033\\ 26\tabcellsep 3\tabcellsep 0.0040\tabcellsep 0.00265\tabcellsep 0.00153\\ 27\tabcellsep 3\tabcellsep 1.0500\tabcellsep 0.62650\tabcellsep 0.36171\end{longtable} \par {\small\itshape [Note: F, F value; n, number of points were the dose rate measured.]} \caption{\label{tab_0}Table 1 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{2} \par \begin{longtable}{P{0.42344322344322344\textwidth}P{0.031135531135531136\textwidth}P{0.09340659340659341\textwidth}P{0.14633699633699634\textwidth}P{0.15567765567765565\textwidth}} Group\tabcellsep n\tabcellsep M ean\tabcellsep Standard deviation\tabcellsep Standard error of mean\\ 1.00\tabcellsep 30\tabcellsep 0.0049\tabcellsep 0.00485\tabcellsep 0.00089\\ 2.00\tabcellsep 45\tabcellsep 10.7451\tabcellsep 12.87781\tabcellsep 1.91971\\ 3.00\tabcellsep 33\tabcellsep 0.0008\tabcellsep 0.00185\tabcellsep 0.00032\\ Total\tabcellsep 108\tabcellsep 4.4787\tabcellsep 9.82373\tabcellsep 0.94529\\ \multicolumn{2}{l}{Results of one-way ANOVA:}\tabcellsep \tabcellsep \tabcellsep \\ \multicolumn{3}{l}{Groups: df = 2, 105; F= 21.79.P = 0.00}\tabcellsep \tabcellsep \\ \multicolumn{4}{l}{ANOVA, analysis of variance; df, degree of freedom;}\tabcellsep \end{longtable} \par {\small\itshape [Note: F, F value; n, number of groups were the dose rate measured.]} \caption{\label{tab_1}Table 2 :}\end{figure} \footnote{© 2016 Global Journals Inc.
