The family decorates go-between people care stone material very much " radioactivity, radiate " problem. Is the radioactivity of stone material strong? How does ability select safe stone capable person? For this, we consulted IT institute physics of earth of Chinese geological university and Dr. Hou Sheng benefit.
Dr. Hou says: "National quality is supervised examine quarantine total bureau releases " set limit to of housing materials radionuclide " the cent of on any account that the standard occupies natural Shi Caigen its radioactivity level is A, B, C3 kind. Among them A kind lowest of product radioactivity level, can use in any circumstances, b kind the product can be used in the facing of inside and outside that divides all buildings beyond face of bedroom interior trim and industrial establishment, c kind stone material of the standard can be used in face of building exterior trim only. " when consumer is selecting stone capable person, the radioactivity level that should ask for its product to manufacturer or agency checks a report, the category that whether its radioactivity level makes clear in the outer packing of stone material product that examines a choose and buy or product manual, will select right stone capable person with this.
