This is totally unacceptable method and you must avoid this kind of sapphires and people who sell this kind of stones.
It’s easy to find Xray treated stones, Only you want to do is keep the stone under sunlight between 10-12.30 in the morning. If stones are treated with X-ray , the stone color will fade. Normally most genuine dealers keep stones under sunlight before purchasing the stones. So if your dealer is reliable and trustworthy don’t be afraid.
