The general goal of the Atmospheric Radiation Measurement (ARM) Program is to improve general circulation and related models of the atmosphere for global and regional prediction (DOE 1990). In order to achieve this goal, the ARM Program is collecting a prodigious volume of data at its first Cloud and The time period selected to do the comparisons between the Radiation Testbed (CART) in the Sout...

Introduction In order to discharge the patients receiving treatment with large radiation doses of 131I for thyroid cancer, it is necessary to measure and evaluate the external dose rates of these patients. The aim of the study was to assess a new method of external dose rate measurement, and to analyze the obtained results as a function of time. Materials and Methods In this study, a telescopic...

The kerma-area product (PKA) is a useful quantity to establish the reference levels in diagnosis of conventional X ray examinations. A KAP meter can be calibrated in laboratory or in situ, where it is used. The patient dose calibrator (PDC) is a new equipment from Radcal that measures PKA. It was manufactured following the IEC 60580 recommendations. The aim of this study was to calibrate the PD...

Considering the extensive usage of electronic systems in Spacecraft and harsh radiation environment in the Space, radiation effects on electronic systems and development of radiation hardening electronic systems have been a topic of research. Researchers are trying to solve this problem at various abstraction levels, starting from fabrication technology to packaging and at system level. This pa...

BACKGROUND C-arm fluoroscopy equipment is important for interventional pain management and can cause radiation injury to physicians and patients. We compared radiation safety education and efforts to reduce the radiation exposure of pain specialists. METHODS A survey of 49 pain specialists was conducted anonymously in 2016. The questionnaire had 16 questions. That questionnaire was about radi...

Ultrasonic flow meters are gaining wide usage in commercial, industrial and medical applications. Major benefits of utilizing this type of flowmeter are higher accuracy, low maintenance (no moving parts), noninvasive flow measurement, and the ability to regularly diagnose health of the meter. This application note is intended as an introduction to ultrasonic time-of-flight (TOF) flow sensing us...

background: although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. one of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. the aim of this study was to determine the physicians' knowledge in radiological examinations. materials and methods:...

Abstract The study using time-lapse microgravity (TLM) data can be helpfull to understand near surface variation caused by hidrological variation. Shallow groundwater highly correlated with density as source, because the changes are very close surface. For several days (or weeks or months), we observe in of water saturated zones. for simplified table changes. purpose this work is application le...

In this paper we describe a system for boat traffic monitoring that has been realized for analyzing and computing statistics of trafic in the Grand Canal in Venice. The system is based on a set of survey cells to monitor about 6 Km of canal. Each survey cell contains three cameras oriented in three directions and covering about 250-300 meters of the canal. This paper presents the segmentation a...
