Propulsion device is studied theoretically which utilizes directly α-particles emitted by radioactive isotope as exhaust gas; random direction of emission and absorption of decay particles in solid is considered; it is found that 11.8 mg of Th-228 deposited/sq cm of α-absorbing surface will produce 0.0039 dyne of thrust; application of system to space propulsion, to attitude control and to extending satellite life times.
