GadoIinium is too expensive (- $100 per gram) to be feasible for large arrays, but detectors using chlorine salts would be less expensive. 5 tons of salt through a 1000 ton active medium (heavy water). If dopants can be used, detection of 1 kt tests at the 100 km range up to about 1000 km is limited primarily by three engineering obstacles. First, the cost of photomultiplier tubes is now around several hundred to a few thousand dollars per tube, while the number of tubes required for remote detection ranges from several hundred thousand to several billion or more.
