【Abstract】 The paper introduces a high-powered embedded module 386SX CPU and the system structure of a portable alpha surface contamination meter based on it, and illustrates in detail the design idea and implementation technology of hardware and software. Through a comparative experiment with a standard source of 239Pu, the detection efficiency and other main characteristics were obtained. The instrument is easy to manipulate, can provide accurate measuring results and therefore meet the needs of most consumers.更多还原
