californium-252—have demonstrated substantial practical applications. One gram of plutonium-238 produces approximately 0.57 watt of thermal power, primarily from alpha-particle decay, and this property has been used in space exploration to provide energy for small thermoelectric-power units. Read Mor Californium-252, with its half-life of approximately 2.6 years, is a strong neutron emitter. The neutrons can pass through materials, and so californium-252 can be used to detect gold and silver, landmines in war zones, and bombs in luggage. Neutron radiography can uncover corrosion and other issues in aeroplanes 252 Cf sources offer a means of performing brachytherapy with neutrons. Conceptually, this is intriguing for tumors in which hypoxia is thought to be a factor in limiting tumor control with standard treatment and which lend themselves to brachytherapy approaches. There has been one randomized study for advanced cervical cancer showing benefit compared with standard brachytherapy with gamma ray sources, but this field still requires considerable development. Remote afterloading devices allow.
