Welcome to another episode of the mother to baby podcast. My name is Chris Stallman, and I'm a genetic counselor, a mom of four, and a teratogen information specialist. So what that means is that I talk to people, so patients, family members, healthcare providers, the general public, about exposures that can happen before pregnancy, during pregnancy, while breastfeeding, and in cases of adoption.

Thank you And an exposure can be anything. So it could be a medication you take. It could be a vaccine. It could be a hair treatment. And in some cases it could be in the place where you work. Today we're going to talk about a very specific exposure, radiation. And we have a very special guest to talk with us today.

Dr. Emily Caffrey is the program director and an assistant professor for the master's in health physics program at the University of Alabama at Birmingham. She is also a certified health physicist that specializes in calculating radiation doses from environmental sources of radiation. Dr. Caffrey, welcome to the show.

Thanks for having me. Excited to be here. Great. So let's get started today. We're going to talk about radiation. Can you tell us a little bit about what radiation is and how people are exposed to it? Yeah, absolutely. Um, you know, radiation is just a form of energy. So there's two types of radiation. There's non ionizing radiation and ionizing radiation.

So non ionizing radiation are lights, microwaves, your cell phone emits non ionizing radiation, things like that. There's also ionizing radiation, and that type of radiation is a little bit higher energy, um, that makes charged particles. Um, and that's the kind of radiation you get when you're talking about a CT scan or an x ray, something like that.

Um, that's ionizing radiation. Uh, and I, and I just want to point out that radiation is all around us. It was present when life first evolved on Earth. It was present when dinosaurs lived. It's still present today. Uh, we live in a radioactive world, and I think a lot of people don't know that. So I'd like to start with, radiation's all around you, and it has been your whole life.

Um, natural radiation comes from space, and it comes from living things that are in the Earth. The Earth's crust is radioactive. You may, if you live in a place that has high radon, um, you may have heard of radon coming from Earth up into your basement. That's a really common source of exposure. Um, and our human bodies and cells have adapted over time to respond to and repair the small amounts of damage you might get from these low levels of ionizing radiation.

So some of the more common forms of radiation, like you described, light, microwaves, CTs, would that also include mammograms and would that increase risks to a pregnancy? Yeah, that doesn't include mammograms. The mammogram is again a low energy type of x ray that's used to image the breast tissue to look for cancer usually.

Um, and You know, just like all
