There are a lot of radio examination instrument category,its basic principle according to occur various effect that between the radial and the material interaction.The most in common use detector has three currently,then the ionization detector,the flicker detector and the semi-conductor detector. This text design a kind of according to MSP430 chip microprocessor carry out of harmful radial monitor machine.This instrument has main function of data collection,real time show,limen value enactment,communication,over limit to give an alarm etc.The text makes detailed represent towards hardware that includes MSP430F4250 chip microprocessor and peripheral circuit. systemic.The software design of the system includes program of data collection,the number display,keyboard,the parameter enactment,the data communication etc, program development tools are both C430 integration built environment and C debugger that are developed for MSP430 series chip microprocessor by IAR company.
