| Abstract: | A new type of portable instrument for measuring soil radon gas and its decay products has been developed and tested. A pulse-ionization chamber, filled with air at ordinary pressure, is designed as the detector of the instrument, which is easy to decontaminate and has the advantages of a large detecting area, simplicity of construction and low cost. The data acquisition and processing system is computerized （pocket computer PC-1500）. The instrument can be applied for both integrated and instantaneous radon measurements. |
