The main uses of cockroaches are: (1) can be used as a heat source. Provides auxiliary energy for vacuum detection and satellites. (2) Pm147 emits low-energy beta rays and is used to manufacture tantalum batteries. As a power source for missile guidance instruments and watches. This type of battery is small and can be used continuously for several years. In addition, helium is also used in portable X-rays, in the preparation of phosphors, in the measurement of thickness and in beacon lights.
