Hipoteza liniowej, bezprogowej zależności (ang. linear, no-threshold, LNT) między dawką promieniowania jonizującego (p.j.) a wywołanym przez nią skutkiem zakłada, że każda, nawet najmniejsza dawka pochłoniętego przez organizm człowieka p.j. może prowadzić do rozwoju nowotworu ciągle stanowi podstawę regulacji w ochronie radiologicznej. W pracy, po krótkiej rekapitulacji genezy hipotezy LNT, podano przykłady wyników analiz epidemiologicznych i badań prowadzonych na zwierzętach doświadczalnych świadczących, że hipoteza ta nie ma podstaw naukowych i że jej stosowanie utrudnia lub uniemożliwia wykorzystanie ekspozycji w niskich dawkach p.j. w diagnostyce i terapii chorób. Pora więc najwyższa aby porzucić fałszywą i szkodliwą hipotezę LNT na rzecz modelu progowego lub hormetycznego opartego na współczesnej wiedzy o działaniu niskich dawek p.j.

The linear, no threshold (LNT) hypothesis assuming that all ionizing radiation is harmful and that even the smallest absorbed dose of radiation may be carcinogenic constitutes the basis of radiation protection regulations. He present review briefly recapitulates the genesis of the LNT dogma and provides examples of results of both epidemiological and experimental studies indicating that the dogma is false and unscientific and, when applied in practice, begets more harm than good. Hence, the time is ripe, if not long overdue, to place cancer risk assessment on the biologically based and fully transparent foundations.
