Abstract Computed tomography (CT) is an instrument that still widely used to diagnose and evaluate patient conditions from images produced by the CT scan process. are formed X-ray beams penetrate patient’s body captured a detector then displayed on monitor screen. A fairly high dose of radiation required produce with resolution, good contrast, low noise. However, this contrary principles ALARA, as reasonably achievable, safety using high-dose radiation. Various efforts reduce have been made....
Radiometric mapping could play a prominent role in locating the host rock or alteration that leads to gold mineralization. Nevertheless, low-sulfidation epithermal deposits, radiometric signatures have be priorly characterized due their geometry. It is comprised of small ore vein system within large zones. The Pongkor mine deposit and was selected for this purpose. method started with surface identification on altered unaltered rocks near using portable spectrometers. They are followed by...
Spectroscopic factors of six low-lying neutron hole states in ${}^{207}\mathrm{Pb}$ were measured with a $(p,d)$ reaction at 65 MeV. The results are compared previous data as well recent escape width ones isobaric analog ${}^{208}\mathrm{Bi}$ into the ${}^{207}\mathrm{Pb}.$ spectroscopic factor for ${2f}_{7/2}$ state shows strong quenching (about 50% sum-rule limit), which suggests existence considerable strengths higher excitation energy region. appearance fragmentation or strength...
Radioisotope Production Facility in Serpong has produced and processed I-131 which can be dispersed to residential areas the environment around Nuclear Zone (SNZ). Measurement of air release dispersion using an old analogue tool is not functioning, only a charcoal filter functioning stack isotope production facility. SNZ been carried out. Therefore, it necessary develop new method measuring concentration combined with equipment from CTBTO measurement (outdoor) SNZ. Direct measurements...
Research of the depositional environment using geological mapping, petrography, gamma-ray (GR) log, palynology, and foraminifera fossils Bojongmanik Formation has led to formation several different conclusions about transition marine environment, which are attractive revisit. The expected results this research determine paleoenvironment Serpong Formations based on elemental geochemistry, development proxies portable X-ray fluorescence (pXRF) in fluvial transitional environments studies,...
Radon (222Rn) and thoron (220Rn) were reported as the highest contributors to natural radiation received by humans. Furthermore, radon has been stated second-highest cause of lung cancer. The concentrations 238U 232Th (the parent nuclide thoron, respectively) in nature vary with geological conditions can be enhanced human activities. Bangka Island Indonesia is one such case tin mining, where environment contains a high amount due island's granite bedrock. This study assesses public's...
Environmental radioactivity surveillance in a large area is undertaken commonly by using ground-based vehicle mounted gamma monitoring system or airborne system. An alternative of drone (unmanned aerial vehicle)-mounted may give advantages saving resources and time, more rapid preparation operation, fewer safer operators, better access coverage area, flexible adjustment flight parameters. A prototype drone-mounted under development BATAN. The design the will consist module other modules e.g....
Abstract Bangka Island with a history of more than 200 years tin mining, has brought along the byproduct heavy minerals which contain radionuclide elements. There are some concerns about this material contributing to natural radiation in environment. In study, car-borne survey was conducted, give an accurate assessment background Island. The measurement indoor and outdoor ambient dose rates 146 houses also conducted for from external exposure received by public. soil samples were collected...

Population growth affects the increase in electrical energy demand Indonesia. The is used to fulfill daily and industrial needs for improving welfare sustainably advance society. Nuclear power plants (NPPs) are technologically advanced, reliable, environmentally friendly electricity generators that can significantly reduce climate change. Current public policies related use of NPPs Indonesia tend bring realization nuclear closer. This study aims provide an overview development uses...
Abstract Digital Survey Meter model SMD-03 has been made. The was built using the GM LND-714 as detector, CD4011 pulse shaping circuit, ATMEGA 8 a counter circuit and 8x2 LCD display. purpose of construction this digital is to develop nuclear instrumentation, especially survey meter, in improving stability counting system. works principle detector convert radiation beam into electric pulses. electrical pulses are inserted inverting invert formed digitals pulse. then ATMega be counted...
Measurements of the electron drift characteristics in a single wire gas counter operated transition region between proportional and self-quenching streamer (SQS) modes have been carried-out. The Ar-based mixtures with small amount ethanol vapor were used as counting gas. As results, different behaviors time response both observed. SQS mode operation gives superior properties on resolution, avalanche size (S/N ratio) stability than those mode. deduced basic data for velocity better...

The number of particle accelerators worldwide increases in the order above 10,000 units every decade, while only very small numbers have been built Indonesia. This fact spurs a need comprehensive analysis cause. A review is urgently required to obtain right direction research & development (R&D) program policy which should be line with world trend and user demand. also produce outcomes impacts capable spread increase accelerator applications high local content. paper describes brief R&D gaps...
Boron Neutron Capture Therapy (BNCT) is an advanced form of radiotherapy technique that potentially superior to all conventional techniques for cancer treatment, as it targeted at killing individual cancerous cells with minimal damage surrounding healthy cells. After decades development, BNCT has reached clinical-trial stages in several countries, mainly treating challenging cancers such malignant brain tumors. The Indonesian consortium already developed the design many cases type using...
Two topics on the phenomena in proportional counters are reported. One is observation of SQS transition pure methane gas under irradiation by 4.5-keV X-rays. The effect a small amount argon was investigated with mixtures (CH/sub 4/:Ar) at various mixing ratios. not observed gas, although it still mixture 99.8:0.2. other measurement electron drift characteristics single-wire counter operated regions. used and to which ethanol vapor added.

Characteristics of gas multiplication and position sensing Ne- Ar-based gases have been investigated compared with each other for sensitive proportional counters. The measurements were carried out in the high region, i.e. transition region from to self-quenching streamer (SQS) mode. As quench gas, CH4 and, some cases, C2H5OH vapor added proper mixing proportions. In sensing, it is advantageous use mixtures which need lower applied anode voltages obtain good S/N ratio. experimental results...
