A Tecnifibre electronic stringing machine. Electronic stringing machines control the tension with a computer-directed electric motor, resulting in fast paced stringing and exceptional accuracy. This is the most common kind of stringing machine found in racquet sport shops. Reliable constant pull stringing machines usually cost $3,000 and more.
Electronic anticoincidence is a method (and its associated hardware) widely used to suppress unwanted, "background" events in high energy physics, experimental particle physics, gamma-ray spectroscopy, gamma-ray astronomy, experimental nuclear physics, and related fields.
It is sensitive to both gamma and hard beta radiation. The tube is approximately 90 mm long, has a diameter of 8.5 mm and operates at a relatively high voltage of 900 volts. The choice of this tube is intended to strike a balance between sensitivity and ruggedness and detects gamma radiation at energy levels of between 20 and 1000 Kev.
Research in this area has focused on the three most common sources of radiation used for these applications, including gamma, electron beam, and x-ray radiation. [17] The mechanisms of radiation damage are different for polymers and metals, since dislocations and grain boundaries do not have real significance in a polymer.
In the United States, non-ionizing radiation is regulated in the Radiation Control for Health and Safety Act of 1968 and the Occupational Safety and Health Act of 1970. [55] In Canada, various federal acts govern non-ionizing radiation by originating source, such as the Radiation Emitting Devices Act, the Canada Consumer Product Safety Act, and ...
For some materials and products that are sensitive to oxidative effects, radiation tolerance levels for electron-beam irradiation may be slightly higher than for gamma exposure. This is due to the higher dose rates and shorter exposure times of e-beam irradiation, which have been shown to reduce the degradative effects of oxygen. [18]
