Although 'Rife devices' are not registered by the U.S. Food and Drug Administration and have been linked to deaths among cancer sufferers, the Seattle Times reported that over 300 people attended the 2006 Rife International Health Conference in Seattle, where dozens of unregistered devices were sold.
Desi dispozitivele Rife nu sunt inregistrate de catre Administratia SUA pentru Alimente si Medicamente si care au fost legate de decese in randul persoanelor care sufera de cancer, Seattle Times a raportat ca peste 300 de persoane au participat la Conferinta Internationala de Sanatate Rife din 2006, din Seattle, unde s-au vandut zeci de dispozitive neinregistrate.
