Gamma Density Meter

nuclear density meter · radioactive density meter · gamma ray density meter · Na-22 density meter · exempt activity density meter

Sodium-22 gamma source at exempt activity (PS7500, < 1000 KBq) — clamp-on, non-contact, suits any pipe shape and the toughest conditions (high temperature, high pressure, abrasive, corrosive). The exempt activity level means no radiation licensing is required — a major operational advantage over Cs-137 systems.
