ABSTRACT:
A dose detector includes a semiconductor radiation detector; a dose counter; and a check counter. The dose detector detects that the semiconductor radiation detector is outputting white noise even in a radiation shielded area and judges that the semiconductor radiation detector is working in a normal manner when dose count data from the dose counter is smaller than predetermined dose boundary data and check count data from the check counter is greater than predetermined lower limit checking data. The dose detector and a dosimeter provided with the dose detector are simple in structure and capable of checking a status of the semiconductor radiation detector safely.
