Abstract: Apparatus and methods for measuring activity of radioactivity at a source location within an environment provided. The method in particular includes measuring emissions using an instrument as a measurement location, which instrument includes a detector, the instrument considering a detector field of view of the environment, which field of view includes a source location and providing an indication of detected emissions for that field of view, correcting the detected emissions to give emitted emissions in respect of that field of view, the correction being achieved by using a correction factor specific for that field of view, the correction factor accounting for one or more field of view format and/or the attenuation between the source location and the detector and/or the distance between the source location and the detector, the emitted emissions being indicative of the activity.
