Abstract: A simplified device is provided for analyzing radiation spectrum. A detector absorbs radioactive particles for generating signal pulses. A signal converter is connected with the detector to discriminate and amplify the signal pulses to be converted into digital pulses. The microcomputer single-chip is connected with the signal converter to measure dual-channel pulse widths for statistical analysis and to measure pulse free count. Under a very low power mode, a pair of information comprising random physical memory spectrum and pulse count are generated. The microcomputer single-chip has a low cost and can be abundantly supplied. Thus, by using the microcomputer single-chip as a touch-driven application, a reading module replaces the high-frequency precision clock. The reading module is built-in for charging voltages with constant-current pulses. Consequently, spectrum analysis is performed for the signal pulses of gamma ray detected by the detector.

Abstract: A digital apparatus is provided for monitoring environment. The apparatus has a high-pressure chamber easy in maintenance. By using a supporting unit, the chamber is stably set in a container. In addition, the supporting unit reduces problem of saturated-humidity absorption so that wastage of utilities and rate of fake signals are both decreased. Thus, the chamber is prevented from mist and vapor for keeping good function.
