Analysis of information sources in references of the Wikipedia article "Americium-241" in English language version.
NASA is running out of the special kind of plutonium needed to power deep space probes, worrying planetary scientists who say the U. S. urgently needs to restart production of plutonium-238.
ESA's nuclear program would likely focus on americium, according to Southwood. [...] Americium-241 has a longer half-life than plutonium-238, meaning it could survive longer in space, but the isotope produces less heat and electricity. Americium is also a greater radiation hazard to humans, according to scientists.
