This is true.

This is true.

Yeah.

Yeah.

It's one of the youngest fields, too, in that respect. It's not steeped in some of the traditions that surgery and medicine are. So, yeah, it's a new field, highly evolving very rapidly, and the technology has changed so much just in, really, in the last decade or two.

As a kid and growing up in Houston, some of my family friends were radiologists. And I remember just like probably an elementary school kid that some of them were talking about radiotherapy. And these were diagnostic radiologists who at the time, CT scanning was pretty new in the 80s. Prior to that in the 70s and then prior to that, it was kind of just a fellowship.

Radiologists would have a Cobalt 60 machine that they would train on for a few weeks and you do a few easy calculations and do some crude treatments. But it really started, it came into its own starting in the 70s and really more into the 80s. And that's when it became its own discipline. The ACR had a separate carve out. And so our residency training is completely independent of diagnostics now.

So we just do, it's an intern year followed by four years of radiation oncology with a little bit of overlap, but not a lot of diagnostic training at all, just because there's so much to do just on the therapeutic side.

radiation itself, the term itself has got a bit of a negative connotation, but basically it's part of the electromagnetic spectrum. So we have everything on the one in the range of increasing energy of photons, which are just particles of light. On the one end, you have radio waves and microwaves. On the other end, you've got infrared and, excuse me, you've got

On the other end, you've got infrared and, excuse me, you've got

ultraviolet and then you get into x-rays and radio waves. And in the middle of all that is the visible spectrum. So when you see, I'm sure everyone's seen the graphs where you've got the rainbow, red, green, blue that we can see, the human eye can only perceive a tiny little narrow spectrum. These are wavelengths.

These are wavelengths.

These are actually wavelengths and energies which are the very low-end energies you have things like radio waves. In that situation, both radio waves and microwaves are what they call non-ionizing. And I know you've talked about this on some of your previous podcasts. I know you had a really good one with Atariwala from Prenuvo. It was a really nice in-depth discussion.

But essentially, the bottom line is that the low-energy stuff that is non-ionizing cannot damage tissue. And that goes all the way up to visible light. Then when you start going to the higher-energy X-rays, that's when you get both X-rays as well as ultraviolet light and then the higher-particle stuff. But basically, the higher you go in the energetics of the particles, the more likely...
