The objective of this work is to develop an automation system for quality control (QC) in the production of Iodine-125 sealed sources, after undergoing the process of laser beam welding (LBW). These sources, also known as Iodine-125 seeds are used, successfully, in the treatment of cancer by brachytherapy, with low-dose rates. Each small seed is composed of a welded titanium capsule with 0.8 mm diameter and 4.5 mm in length, containing Iodine-125 adsorbed on an internal silver wire. The seeds are implanted in the human prostate to irradiate the tumor and treat the cancerous cells. The technology to automate the quality control system in the manufacture of lodine-125 seeds consists in developing and associate mechanical parts, electronic components and pneumatic circuits to control machines and processes. The automation technology for Iodine-125 seed production developed in this work employs programmable logic controller (PLC), step motors, drivers of control, electrical-electronic interfaces, photoelectric sensors, interfaces of communication and software development. Industrial automation plays an important role in the production of Iodine-125 seeds, with higher productivity and high standard of quality, facilitating the implementation and operation of processes with good manufacturing practices (GMP). Nowadays, the Radiation Technology Centre at IPEN-CNEN/SP imports and distributes 36,000 lodine-125 seeds per year for clinics and hospitals in the whole country. However, the Brazilian potential market is of 8,000 lodine-125 seeds per month. Therefore, the local production of these radioactive seeds has become a priority for the Institute, aiming to reduce the price and increase the supply to the population in Brazil. 展开更多

Three-mile Limit是英美国际法中较古老的一个原则,讲"领海宽度"的。当时划分领海标准有两种:最初是"目力所及范围",后来是"大炮射程以内",从前,人们把Three-mile Limit译为"三英里原则",这同... Three-mile Limit是英美国际法中较古老的一个原则,讲"领海宽度"的。当时划分领海标准有两种:最初是"目力所及范围",后来是"大炮射程以内",从前,人们把Three-mile Limit译为"三英里原则",这同当时的"大炮射程距离"(Range of Cannon Shot)实际上是一回事,因为当时的大炮射程为三英里。现在有人认为领海宽度应以"海里"(浬)计算,故在一些论国际法或海洋法的论文或译著中,把Three-mile Limit改译为" 展开更多
