The M-1950 U.S. military lensatic field compass with self-luminous lighting (designated the Model 3H by Cammenga) is fitted with self-luminous tritium vial lighting. Under U.S. military specification (MIL-SPEC) performance criteria, ten pre-production samples of the M-1950 are required to meet a battery of performance, durability, and accuracy ...
Some military compasses, like the U.S. M-1950 (Cammenga 3H) military lensatic compass, the Silva 4b Militaire, and the Suunto M-5N(T) contain the radioactive material tritium (3 1 H) and a combination of phosphors. [37] The U.S. M-1950 equipped with self-luminous lighting contains 120 mCi (millicuries) of tritium.
The successful prediction of a stock's future price could yield significant profit. The efficient market hypothesis suggests that stock prices reflect all currently available information and any price changes that are not based on newly revealed information thus are inherently unpredictable. Others disagree and those with this viewpoint possess ...
Tritium excretion can be accelerated further by increasing water intake to 3–4 liters/day. [11] Direct, short-term exposure to small amounts of tritium is mostly harmless. If a tritium tube breaks, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.

A C79 Optical Sight. The C79 optical sight (SpecterOS3.4x) is a telescopic sight manufactured by Elcan.A variant, the M145 Machine Gun Optic is in use by the US military. It is 3.4×28, meaning 3.4x magnification, and a 28mm diameter objective lens.
Tritium is only a health threat if ingested or inhaled. Since tritium is a gas, if a tritium tube breaks, the gas dissipates in the air and is diluted to safe concentrations. Tritium has a half-life of 12.32 years, so the brightness of a tritium light source will decline to half its initial value in that time.
