The invention relates a radioactive source bin which comprises a basal body and a radioactive source chamber and a shielding body bin which are distributed in the basal body, wherein the shielding body bin is internally provided with a high density shielding body; the radioactive source chamber is a step-type round hole, and the shielding body bin is a cup-shaped groove which is covered on the periphery of a radial hole of the radioactive source chamber; and the high density shielding body is nested in the cup-shaped groove, the outer end part of the shielding body is plugged by a plugging block, a low density window is engraved on the shielding body in radial direction, and the window is communicated with an alignment hole in the basal body. The invention also relates to a drill collar with the radioactive source bin, the middle of the drill collar is provided with more than two righting wings, one of the righting wings is provided with a groove, and the exterior of the groove and a cover plate are cooperated to form a closed bin; and the radioactive source bin approaches to one side of the closed bin, and the alignment hole of the bin inclines to one side of the closed bin. The radioactive source bin and the drill collar provided by the invention have the advantages that a radioactive source can not drop off all the same even if in the harsh drilling environment, the use is safe and reliable and the measuring accuracy is high.
