What Does Jáchymov Treat?

Jáchymov is the leading European spa for inflammatory-rheumatic diseases — a specialisation where the radon therapy produces effects that thermal water and moor packs alone cannot achieve.

– Rheumatoid arthritis — alpha radiation activates superoxide dismutase and catalase, suppressing inflammatory flares (★★★) – Bechterew’s disease (ankylosing spondylitis) — radon baths inhibit bony stiffening, improve spinal mobility (★★★) – Psoriatic arthritis — combined effect on skin and joints – arthrosis — endorphin release relieves pain, slows cartilage degradation – Gout — radon promotes uric acid excretion via liver enzymes – Fibromyalgia — endorphin release alleviates generalised pain – Chronic polyarthritis — one course per year keeps many patients symptom-free for 9–12 months

Treatments in Jáchymov

Radon bath: The core treatment. The patient bathes for 20 minutes in 36–38 °C water containing dissolved radon at 1–3 kBq/l. The alpha particles emitted by the radon penetrate only 40 micrometres into the skin — less than the thickness of a human hair. They activate the production of superoxide dismutase (SOD), catalase and glutathione peroxidase — enzymes that neutralise the free radicals overproduced during chronic inflammation and responsible for joint destruction. The result is not symptomatic pain relief but a fundamental reduction in inflammatory activity that lasts for months. After the bath, a 30-minute rest period allows the radon to distribute through the body. A full course comprises 10–15 baths. 1 — learn more.

Radon inhalation: The patient breathes radon-containing air in a special chamber for 15–20 minutes. Absorption through the lungs delivers the alpha emitter systemically via the bloodstream, reaching joints far from the skin surface. Inhalation is prescribed two to three times per week and complements the transdermal absorption from the baths.

Radon drinking cure: Small quantities of radon-containing water are drunk — a gentle systemic supplement to bathing and inhalation. The radon drinking cure has been a traditional application in Jáchymov since 1906.

physiotherapy: Uniquely important in Jáchymov. The radon therapy relieves pain so effectively that patients can perform movements during physiotherapy that were impossible before the course. The physiotherapists exploit this therapeutic window for intensive joint mobilisation and muscle strengthening — work that would be too painful without the preceding radon treatment.

History and Atmosphere

Jáchymov has a double history as a silver mine and the birthplace of radioactivity research. The Joachimsthaler — the silver coin minted here from 1520 — gave the dollar its name (Thaler → dollar). When the silver deposits were exhausted, uranium ore mining began in 1853 — initially for glass and ceramics, later for atomic research.

In 1898, Marie Curie isolated radium from Jáchymov pitchblende, winning the Nobel Prize. She visited the town personally to source material for her research. The healing effect of the radon-containing mine water on the miners — many of whom suffered from joint pain that disappeared in the warm mine tunnels — led to the opening of the first radon spa in the world in 1906. The Radium Palace, a stunning Art Nouveau building, remains the architectural symbol of the resort.

Jáchymov is a small town of 3,000 in a forested mountain landscape. The spa hotels are scattered through the town and surrounding woods. There are no colonnades, no concert halls, no promenades — Jáchymov is not a spa resort for strolling and socialising. It is a focused medical facility for patients with serious inflammatory joint diseases who are seeking a treatment that exists nowhere else in Central Europe. The mountain air at 700 metres is clean and crisp — ideal for the walking therapy that accompanies the radon treatment.

Getting to Jáchymov from Germany

Jáchymov lies in the Bohemian Ore Mountains on the Saxon border. From Dresden it is 130 kilometres (2 hours) — the route climbs through forested mountain roads, scenic but winding. From Nuremberg it is 200 kilometres (2 hours 30 minutes). The door-to-door transfer with German-speaking driver is strongly recommended due to the mountain approach. The nearest railway station is Ostrov nad Ohří (10 km). Karlovy Vary International Airport is 25 kilometres away.
