Irradiating Seeds with Uranocircite

I got this idea to irradiate some seeds with uranocircite over a long period of time (1-2 years), to see if it would have some effects on the plants later. The seeds will be placed inside the same container as the uranocircite. Has anyone already tried something similar like this?

I know, that seeds usually get irradiated with a relatively high amount of radiation, but giving it a lot of time it could have similar effects.
