Russian company Isotope (part of ROSATOM State Atomic Energy Corporation) supplied Cm-244 alpha-emitter to Physical Research Laboratory (Ahmedabad, India).
Radionuclide curium-244 (Cm-244) manufactured by Russian “State Scientific Center - Research Institute of Atomic Reactors” (JSC SSC RIAR) is a pure alpha-emitter that enables sources to determine chemical composition of any rocks and soils.
It will be installed on the Alpha Proton X-Ray Spectrometer (APXS) aimed at analyzing the lunar surface within the India's second lunar exploration mission Chandrayaan-2. The launch of spacecraft is scheduled for 2018.
Earlier Russia has already supplied similar products to USA for launching of three NASA’s expeditions - Mars Pathfinder (1997), Opportunity (2004) and Curiosity (2012) dedicated to explore rock chemistry on Mars.
In 2014 the World’s first soft landing of the Rosetta spacecraft on Comet Churyumov-Gerasimenko took place. The lander Philae, equipped with Russian made Cm-244 transmitted high-accuracy data about Comet’s surface composition to Earth.
In the world Cm-244 production is carried out only in two countries - Russia and the USA.
