Treatments using non-ionising (e.g. laser) radiation and sound

Some treatments – involving, for example, the use of laser beams, light, ultrasound or radiofrequency – may pose risks to human tissue. Since June 2019, treatments using radiation and sound have therefore been regulated by a Federal Act and an associated Ordinance. From 1 June 2024, persons carrying out such treatments require a certificate of competence.
