Answer:
Small amounts of a mutagen often do not have an effect on health
Step-by-step explanation:
X-ray is a form of electromagnetic radiation used as an imaging tool to view internal structures. X-ray radiation occurs when a charged particle hits a material at a high wavelength.
Exposure to X-ray radiation has been shown to cause serious health concerns as they are known to be mutation-inducing i.e. mutagenic, when exposed to in high quantities or doses. Therefore, in the case of Maria who was exposed to a small amount of X-ray radiation, the doctor would likely tell her that small amounts of a mutagen (X-ray) often do not have an effect on health.
