Abstract
Disclosed is a shielding device of source mounting and demounting for a nuclear logging instrument including a device base and a shielding device body. The device base is directly placed on the ground or a well stand. The shielding device body is slidably assembled in an embedded slideway of the device base. During source mounting operation, a worker takes a source from a source container, and a radioactive source passes through the shielding device body through a circular hole of the shielding device body to be installed. During the source demounting operation, the radioactive source and the worker are arranged on both sides of the shielding device body during the operation at an instrument end. Through such design, the worker is allowed to calmly mount and demount the source in a relatively low radiation field.
