Production method of controllable 210 Po-Be isotope neutron source and controllable 210 Po-Be isotope neutron source

The invention provides a production method of a controllable 210 Po-Be isotope neutron source. The production method comprises the following steps in sequence: (1) providing a container, a driving part, a cylindrical metal matrix and a Be target; (2) arranging a 209Bi-containing compound in a partial region of the side surface of the cylindrical metal matrix; (3) carrying out irradiation treatmenton the cylindrical metal matrix; and (4) placing the Be target and the cylindrical metal matrix in the container in an isolated manner, starting the driving part, enabling the cylindrical metal matrix to rotate under the action of the driving part, and changing the relative position of the area, provided with the 209Bi-containing compound, of the cylindrical metal matrix and the Be target. According to the invention, the 209Bi-containing compound is arranged on the side surface of the cylindrical metal matrix; radioactive operation is not involved in the arrangement. The production method isconvenient to operate and
