A bare, cylindrical vial GTLS constructed of 0.1 mm thick glass that is 10 mm long and 0.5 mm in diameter will yield a surface dose rate of 100 millirads per hour per curie. If the same vial were instead constructed of 1 mm thick glass and enclosed in a plastic covering that is 2–3 mm thick, the GTLS will yield a surface dose rate of 1 ...

Fishing rod float. Lake Baikal. Eastern Siberia.
