Cerenkov counting.
When auditing research laboratories, health physics personnel are often alarmed to find liquid scintillation vials that only contain filters and no cocktail. They are then surprised when lab personnel state that they don't need cocktail to count their samples. While not frequently used by the health physicist, counting of samples by using Cerenkov radiation is valid and advantageous when correctly used.
