The Ranger-X5 radar system has a Transmit/Receive (TR) Limiter that contain a small amount
of tritium (see Volume 1, Section 4, Vendor Documentation). The TR Limiter protects the
sensitive receiver components from the high-energy burst of the transmit RF burst. The TR
Limiter is a passive device.
Figure 50. TR Limiter (NWLIM8896-57)
The receiver protector tubes are individually sealed units and normal handling does not
present
any
radioactive problems. The manufacture of TR Limiters complies with 49 CFR 173.422. The TR Limiters are
parts in compliance with 29 CFR 1910.1200. The TR Limiters are classified as “electron tubes” in compliance
with 10 CFR 30.15 (a) (8). See Volume 1, Section 4, Vendor Documentation for the Material Safety Data
Sheet (MSDS), which includes information about special care and disposal of the TR Limiter.
