This is not my field. Replace every "exposure" with "dose" in the article and the main point still stands. I’m sorry about the mix-up. This is not my field.

Replace every “exposure” with “dose” in the article and the main point still stands.

In medical physics, both "dose" and "exposure" have technical definitions, and the two are historically related but not the same. Exposure is the amount of charge liberated per unit mass due to ionizing radiation in air, and dose is the amount of energy per unit mass that is absorbed by a system as a result of ionizing radiation. Dose is the quantity that is measured in rems (or, in SI units, in Grays [Gy]).
