The radiation of a single gem is so small that the wearer completely ignores it. But with a large number of jewelry stores, there will be some overlapping effects, especially some large rare treasures. Because they are large, the radiation content may be more. There is no standard for specific radioactivity, because it is related to the radioactive content of specific gemstones.
There is also an old saying that "people keep jade for three years, and jade keeps people for a lifetime". Why jadeite relied on people to support people at first, rather than supporting people, may be related to this.
