Response:

Pequeñas cantidades de un mutágeno no suelen afectar la salud

Clarificación:

Los rayos X son una forma de radiación electromagnética utilizada como herramienta de imagen para observar las estructuras internas. La radiación de rayos X se produce cuando una partícula cargada impacta un material a una alta longitud de onda.

La exposición a la radiación de rayos X se ha demostrado que causa serios problemas de salud, ya que se conocen por inducir mutaciones, es decir, son mutagénicos, especialmente si se presentan en grandes cantidades o dosis. Por lo tanto, en el caso de María, quien estuvo expuesta a una pequeña cantidad de radiación por rayos X, es probable que el médico le informe que pequeñas cantidades de un mutágeno (rayos X) generalmente no tienen un impacto en la salud.
