Abstract
One aspect of the present invention relates to a recovery method of 226Ra, and the recovery method of 226Ra includes a step (A1) of immersing a solid-state 226Ra containing substance and a carrier having a function of adsorbing 226Ra ions in a processing solution, and then irradiating the processing solution with ultrasonic waves.
Claims9
A recovery method of 226Ra comprising a step (A1) of immersing a solid-state 226Ra-containing substance and a carrier having a function of adsorbing 226Ra ions in a processing solution to obtain a processing liquid, the processing liquid comprising the solid-state 226Ra-containing substance, the carrier and the processing solution, and then irradiating the processing liquid with ultrasonic waves.
A production method of a 226Ra solution, comprising:
- a step (A1) of immersing a solid-state 226Ra-containing substance and a carrier having a function of adsorbing 226Ra ions in a processing solution, and then irradiating the processing solution with ultrasonic waves;
- a step (A2) of separating the carrier from the processing solution;
- and
- a step (A3) of eluting 226Ra from the carrier separated in the step (A2) using an acid.
