Through the analysis of the radioactive specific activity, exposures inside and outside the index in decor wood, the results shows that the radioactive content is different in different logs, are 40K > 226Ra > 232Th and the radioactive content of E0 Composite board is higher than E1. Analysis of samples can be used for indoor decoration materials.

The system have one SIMATIC S7-400H controller and 7 distributed I/Os. The PROFIBUS-DP dual redundant network is used in the system to control the site alarm functions. If one network is failure, the other network can switch to transfer data automatically. The reliability and maintainability are enhanced by the combination of the hardware and software of PLC. It can save the human and material resources. The result of the system test shows that the functions of the system correct, it can realized the requirements of specification. The system realized the network and the digital. The system reliability was improved.

In order to detect whether the nuclear fuel components are damaged when replacing them in the reactor of a nuclear power plant, a new sip-suction-online device is designed and introduced in this paper. The device is based on ARM9 processor, embedded linux operating system and Qt Embedded applications, with the functions of detection, display, control, alarm and storage. It can timely, accurately and reliably detect whether the nuclear fuel components are damaged in the environment of a nuclear power plant.

It introduced the design ideas, the technical specifications and major performance for Model BH1217G--the latest Ultra-low Background Alpha Counting Measurement System, and gave the measured result of the actual samples. This system is chiefly used to monitor the personal inner irradiation situation which people worked in radioactive environments by checked their urine, and also can measure low level ALPHA radioactivity.
