The core mechanism is well supported: ionizing radiation splits water in cells, producing hydroxyl radicals that cause DNA strand breaks and other genetic damage. The sources do not specifically address the 'cytoplasm' detail, and they also describe direct DNA damage, which the claim neither denies nor mentions. The extraction faithfully paraphrases the passage.
What was said
… For example, a lot of people think, well, ionizing radiation hits your genetic code and causes a mutation. That's actually not how it works most of the time. What actually works is that the ionizing radiation strikes the cytoplasm of your cell and heats up and alters water and creates hydroxyls, so OH molecules, that then cause the genetic damage, single-strand or double-strand breaks. You can have a wave of hydroxyl molecules or other reactive oxygen species generated after exposure to different forms of radiation, but, you know, some types of radiation can't even penetrate the top layer of your skin cells. …

Supports. Water radiolysis by ionizing radiation produces hydroxyl radicals that react with DNA and cause strand breaks; this is described as indirect DNA damage.[2][3][4][7]
Supports. Hydroxyl radicals are described as a major mediator of radiation-induced DNA damage, including single- and double-strand breaks.[4][6][7]
Supports. Educational sources describe radiation heating and ionizing water and molecules, with ionization and reactive species damaging biomolecules including DNA.[5][8]
Supports. The FDA, as quoted by Snopes, states that energy from ionizing radiation can damage DNA and cause genetic changes.[1]
Context. Sources also describe direct action, where radiation deposits energy in the DNA itself, so the claim describes only the indirect pathway. This is an omission rather than a contradiction.[2][5]
Context. The sources do not say whether the damage originates in the cytoplasm specifically, so that detail is not confirmed or refuted.[2][5]
