Electrical power sources used in outer planet missions are a key enabling technology for data acquisition and communications. Power sources generate electricity from the thermal energy from alpha decay of the radioisotope 238Pu via thermo-electric conversion. Production of 238Pu requires specialist facilities including a nuclear reactor and reprocessing plants that are expensive to build and Americium-241 (241Am) is used in very small quantities in household ionization smoke detectors. Americium is similar to plutonium (Pu) in many ways. While the public accepts the use of minute quantities of 241Am in smoke detectors in their homes, the public reaction to transporting any quantity of 239Pu under suitable controls is very different.

Backscatter method. Make first a hole with the help of guide plate and insert the test probe. MC Portaprobe operates by emitting radiation from two safety-sealed radioactive sources: cesium-137, a gamma emitter for density measurement, and americium-241:beryllium, a neutron emitter for moisture measurement.
