Tosh tanlash bo'yicha takliflar

1. Tosh radioaktiv sertifikatga ega. Iltimos, uni sotib olayotganda sotuvchidan so'rang. Sertifikatsiz xarid qilmang. Shu bilan birga, uyni bezash uchun A toifali mahsulotlarni tanlashga e'tibor bering.
2. Marmar va granitni tanlashda birinchi navbatda marmar e'tiborga olinishi kerak. Oddiy sharoitlarda granitning radioaktivligi marmarnikidan kattaroqdir.
3. Generally, the consideration of stone materials should be black, gray white, flesh red, green and red. From the perspective of radioactivity, the order from high to low is: red>green>flesh red>gray white>white>qora, asosan bu tartibda.
