Abstract

A baseline river flow estimation has been conducted in the area of Duncok and Ngrejok Wetan Gunung Kidul, using VLF-EM and VLF-EM-VGRAD methods to find out VLF response of tilt angle mode. Interpretation is done from VLF and VLF-EM-VGRAD data of tilt angle and ellipticity to estimate underground stream that is interpreted qualitatively and quantitatively. Measurements were made on July 22-26, 2014. The data were processed by using uses MATLAB R2014a computational language. This qualitative interpretation is done by processing data filtered by Moving Average through Karous-Hajelt filter and Fraser filter so as to show the anomaly of underground conductive object. Of the two methods used, the most effective method is with VLF EM, it can be seen from the result of the Karous Hjelt filter shows the contrast resistivity in VLF EM compared to VLF-EM-Vgrad

Abstract

Analysis Of Radiation In The Operating Room From C-Arm Radiation By Thermoluminiscence Dose (TLD).Measurement of C-arm radiation exposure in the surgery room is very important to know the amount of radiation scattered, so that we can ascertain the amount of radiation received by the doctor, nurse or radiology operator in the room. C-armRadiation dose was meansured in the surgery room at Awal Bross Hospital, Bekasi, by using Thermoluminenscence Dosimeters. Radiation dose in the operation room was meansured at 12 points in the room and 1 point at the center of the room. From this study, the highest radiation dose is at the center of the room, 1,021 mSv. The maximum radiation dose at 1 meter from the center is 0,047 mSv and the minimum dose is 0,013 mSv. The maximum dose at 2 metrs from the center of the room is 0,039 mSv and the minimum dose is 0,028 mSv. This all result is still in dose limit value for one examination.
