What acids, solvents is lithium-6 fluoride soluble in (other than HF)?

$ce{LiF}$ is quite insoluble in water, and I’m trying to use some water-soluble acid or solvent to dissolve $ce{^6LiF}$ (95% enriched) in. I’m not a chemistry person, I’m a radiation detection person, and I have very little idea of chemistry. Could anyone please help?
