Abstract:
1. A method of collecting data on radioactive material within an environment, the method comprising; providing an instrument; providing a set of one or more pre-suggested positions before a detector unit is provided at a first position; positioning the detector unit at the first position relative to the environment; collecting at least a part of a first set of data on the environment from the first position using the detector unit, the first set of data including a count from the radioactive material and/or a count rate for the radioactive material; and collecting at least a part of one or more subsequent sets of data on the environment from one or more subsequent positions using the detector unit, the at least a part of one or more subsequent sets of data including a count from the radioactive material and/or a count rate for the radioactive material, wherein one or more of the subsequent positions is different from the first position so as to provide one or more different subsequent positions; wherein one or more of the different subsequent positions is not in the set of one or more pre-suggested positions and the one or more of the different subsequent positions for the detector unit is determined by the instrument by, at least in part, considering the count from the radioactive material in the data of one or more of the sets of data previously collected and/or by considering the count rate for the radioactive material in the data of one or more of the sets of data previously collected.
