| Abstract: | At present, portable instruments for radon measurement are large in volume, poor in meas- urement sensitivity and digitized degree. We have designed a new portable instrument for radon measure- ment with GPS, new data acquisition and control circuit based on ARMT. It has higher sensitivity, accuracy and velocity. Embedded operation system （uc/OS-II） was used in software design for increasing stability and operability. The results of field assay showed that the instrument can be used for radon measurement in geologic and hydrographic survey. |
