Patent ID: 8190398

Claim:
An environmental-radioactivity measurement/management system, comprising: a first measurement instrument for making gross measurement of radiation; a server which manages an environmental-radioactivity measurement service-operation; said environmental-radioactivity measurement service-operation being an operation of sampling measurement specimens at a measurement place requested by a client, making said gross measurement of radiation by using said first measurement instrument deployed at a worksite, sending result of said gross measurement and said measurement specimens to an analysis center, and, at said analysis center, calculating amounts of radioactive nuclides of said measurement specimens at a sampling point-in-time by analyzing both said gross measurement made by said first measurement instrument and further measurement of radiation of said measurement specimens at said analysis center, and reporting said calculated amounts to said client, said server, comprising: a contract management unit which manages measurement contract information which includes said measurement place requested by said client; and a measurement-instrument calibration management unit which manages a calibration schedule of said first measurement instrument deployed at a worksite; wherein said measurement-instrument calibration management unit issues an instruction so that an alternative first measurement instrument will be delivered within a calibration expiration time-limit of said first measurement instrument, said first measurement instrument being deployed at said measurement place which is requested by said client based on said measurement contract information managed by said contract management unit, and so that said first measurement instrument will be deployed until at that time the first measurement instrument will be recalled in exchange for said delivery of said alternative first measurement instrument, and said first measurement instrument will be designated for recalibration.
