Quality limits for medical bath waters Chemical effects can be used in bath tubs if –no disinfection –Concentration in tub is H 2 S > 10 mg/l Radon > 1 kBq/l CO 2 > 1 g/l Brine 10-150 g/l Physical effects can be used in pools if –water is disinfected –temperature >30 °C Which elements in spring waters are effective in bath therapy?

Primary Efficacy Variable Only validated parameters should be used. Only one efficacy parameter is to defined. Endpoints used to determine efficacy should be clearly specified. Multiple parameters should be assembled to one score parameter. An efficacy threshold is to defined.

How Dosis can be calculated by Skin-Clearance? Dosis = Skin-Clearance x Area x Concentration x Time Dosis limit is the amount on the Skin Skin-Clearance is realized by optimal Penetration situation ( Bath, wet Skin, Okklusion Effect of temperature (Q 10. = 1,1-1,4) but skin temperature only low variable

The main effect of radon Radon and the dissolution products penetrate into the horny layer. Alpha-radiation from the horny layer is effective in the stratum spinosum. Dissolution products cannnot penetrate into the living tissue. Radon and the dissolution products penetrate into the horny layer.
