It's definitely genuine Hokutolite from Tamagawa Onsen!! ★★《Attention》★★ The Geiger counter in the images is an Inspector Plus made by SE International, Inc. It detects alpha, beta, gamma, and X-rays with high sensitivity. Simple counters that only detect gamma rays are sold online, but they show smaller values because they cover fewer types of radiation. I have borrowed and compared measurements with various types of counters at Tamagawa Onsen, and the simple ones showed smaller numbers. ◎ The values vary depending on the measurement method. Hokutolite gives 10 different measurement results when measured 10 times. Even so, this stone is a good quality Hokutolite that consistently gives good values!! ◆ The seller, who was born in Akita, is offering Hokutolite collected before it was designated as a natural monument, inherited from their great-grandfather. ● You may be worried about purchasing, but I weigh and measure the radiation levels just before shipping and record a video before sending it. I offer the video free of charge upon request!! ＊ You can also purchase it after measuring the radiation levels in front of you and handing it over. Please see, touch, and measure it to confirm that it is genuine before purchasing. ◆ "Hokutolite" is a valuable mineral found only in two places in the world: "Tamagawa Onsen, Akita Prefecture" and "Beitou Hot Spring, Taiwan."
