background: hot lab is a specially designed room in a nuclear medicine hospital where the radiopharmaceuticals are delivered, stored and prepared for dispensing. 99mo/99mtc-generator is the major source in the hot lab used for various medical imaging. it is important to maintain a standard for hot lab procedures to optimize the patient care and minimize radiation exposure to all nuclear medicin...
We carried out a questionnaire survey to determine the actual situation of radiation safety management measures in all medical institutions in Japan that had nuclear medicine facilities. The questionnaire consisted of questions concerning the evaluation of shielding capacity; radiation measurement; periodic checks of installations, equipment, and protection instruments; and the calibration of r...
Radiation monitoring and inspecting instruments are important tools for the measurement of radiation dose rate or radioactivity. Now in Taiwan, there are five laboratories (processors) capable of providing calibrations for radiation monitoring and inspecting instruments. All these five laboratories have been accredited by the Chinese National Laboratory Accreditation (CNLA). In the past, there ...
The objective of calibrating TLD badges and radiation survey meters demand that accurate dose gets to the TLDs and radiation survey meters. A lead block mould and an ICRU slab phantom had been designed and constructed to collimate the panoramic Cs-137 source at the secondary standards dosimetry laboratory (SSDL) by experts at the National Nuclear Research Institute (NNRI) workshop of the Ghana ...
Neutrons constitute a major component in the radiation fi eld outside the shielding of particle accelerators. Consequently appropriate neutron dose meters are needed to survey the radiation levels. A thermo-luminescence based neutron dosemeter is used at the UNILAC as well as at the SIS. It has been modifi ed to improve the response for high energetic neutrons (extended range). We report on a t...
It is an auspicious time for this first-ever ISRR special session on the topic of underwater robotics. Underwater robots are now performing high-resolution acoustic, optical, and physical oceanographic surveys in the deep ocean that previously were considered impractical or infeasible. For example: in 2001 the Argo II underwater robotic vehicle, [1], was employed to discover the first off-axis ...
To develop indigenous alternative and renewable energy resources, long-term subsidy programs (1986–1991 and 2000–present) for solar water heaters have been enforced in Taiwan. By the end of 2010, the total installed area of solar collectors had exceeded 2 million square meters. However, over 98% of solar water heaters were used in residential systems for hot water production, with the areas of ...
Different types of telecommunication antennas, especially BTS antennas established in residential areas, emit radio frequency (RF) electromagnetic energy. So, community concerns over the health effects from their exposure are growing. To perform hazard assessment related to radio frequency radiation both at telecommunications sites and residential areas, and also to ensure compliance with natio...
