摘要：

Carbon nanocapsules containing nanometer-size particles of molybdenum carbide hal le been irradiated by neutrons of flux 10(14) N cm(-2) s(-1) for 6 days. The gamma-ray spectrometry shows 10(10) Bq g(-1) of Mo-99 which is transformed from Mo-89 and decays into Tc-99. Our investigation by transmission electron microscopy indicates that the nanocapsule is robust against our neutron irradiation; and used as a container for radioactive materials and tracer elements. The contents oi rile capsule in the nanometer scale are activated and transformed into other nuclei.
