PROBLEM TO BE SOLVED: To provide a bed for bedrock bathing which allows radium radiation rays to be generated at the rear side of a bedrock body to be involved in the development of radon gas and anion through multiple ventilation passages and allows the radon gas and the anion to be discharged from small holes opened in the circumference of the head part of a human body lying supine through the use of the convection of the ventilation. SOLUTION: A heating part 18 includes a hyperthermic board 13; a hyperthermic pipe 15 for circulating warm water in the hyperthermic board 13; and a warm water supply source for supplying the warm water to the hyperthermic pipe 15. The bedrock body 9 includes multiple board shape radium ores 10 having smoothly finished a upper surface; a fixing body 11 for fixing and arranging each radium ore 10; and the multiple ventilation passages 12 arranged under the fixing body 11 along the longitudinal direction of a bed body 3. The rear parts of the ventilation passages 12 are communicated with the air intake ports 20 of the bed body 3 positioned lower than the ventilation passages 12. The front parts of the passages are communicated with the multiple small holes 6 opened in the circumference of a pillow 5 which is placed on the upper surface of the front of the bed body 3 via an air collecting chamber 21 arranged in the front. An insulation material 14 is filled in a part under the hyperthermic board 13 of the bed body 3. COPYRIGHT: (C)2006,JPO&NCIPI
