Of these, the Soviet Union performed 116 tests in the atmosphere, and 340 underground. While some of the nuclear tests at Semipalatinsk involved atomic explosions, other experiments were designed to study the impact of conventional explosives on plutonium and highly enriched uranium

Pacemakers are used to stimulate a regular heartbeat when the body's natural electrical pacing system is irregular or not transmitting properly. Over the years, various power sources have been used for pacemakers, including thermoelectric batteries containing 2 to 4 curies of plutonium-238 (88 year half-life). As the term "thermoelectric" implies, the heat from the decaying plutonium is used to generate the electricity that stimulates the heart. At present (2003), there are between 50 and 100 p

Powering spacecraft with solar energy may not seem like a challenge, given how intense the Sun’s light can feel on Earth. Spacecraft near the Earth use large solar panels to harness the Sun for the electricity needed to run their communications systems and science instruments. However, the farther into space you go, the weaker the Sun’s light becomes and the less useful it is for powering systems with solar panels. Even in the inner solar system, spacecraft such as lunar or Mars rovers need alt
