A method of preparing a radioactive material to serve as a radiation source for an intra-lumen imaging capsule, comprising:
- receiving a radioactive substance having grains in powder form;
- forming a solid pellet wherein the grains of the radioactive substance are dispersed homogenously in the pellet and surrounded by less dense materials having lower radiation absorption;
- wherein said forming comprises:
- mixing the radioactive substance with a polymer binder to form the solid pellet;
- and
- curing the mixture while rotating it so that the grains of the radioactive substance don't settle and ruin the homogenous dispersion.
