With the development of diamond synthesis at low pressure

the CVD diamond properties including elec- tronic characteristics have improved continuously. Now the fabrication of electronic devices based on the CVD dia- mond has been one of hot research subjects in this field. Due to many unique advantages

such as high signal-noise ratio

fast time response

and normal output in extremely harsh surrounding

the CVD diamond radiation detector has attracted more and more interest. In this paper

we have reviewed the development and status of the CVD diamond radiation detector. The prospect of this detector is described.
