Abstract
The invention relates to a device and a method for counting elementary particles emitted by a fluid, the device comprising a line for transferring the fluid and, outside the line, detection means (6a) for detecting the particles that are attenuated by a wall of the line and/or by this fluid.A counting device according to the invention includes at least one counting portion (4a) of oblong cross section which joins together two adjacent portions of the line having a larger flow section and which has an [internal height (h)/internal width (l)] ratio of 20% or less, in which the internal height and the internal width represent the smallest and largest transverse dimensions respectively of the portion, these being measured along two approximately perpendicular directions, said detection means extending transversely to this portion, facing its entire internal width and on either side thereof.
