So quick announcement, we're not doing nuclear activation

So we'll likely just do this next Friday.

And instead, we'll have the whole recitation

I also want to say thanks to whoever said, please write

with a publisher, or a potential publisher,

Because as I think as you guys have seen,

there's no one reading that does this course justice.

like most of what we're going to go into today--

And where do cosmic rays come from, and what are they?

So thanks to whoever said that, because it spurred me off

on a let's make this into a book kind of thing.

Want to quickly review what we did last time.

We went over all the different units of dose and radiation

which is pretty much just valid for those measurements in air.

And I realized that yesterday I brought in the civil defense

power or exponential attenuation equations.

Into units of increased risk, or sieverts,

which is just gray times a bunch of quality factors, which

are either tabulated, or I'd like to see somewhat better

They are calculated sometimes, but by empirical relations,

Biomeasurements tend to be pretty sloppy,

and I'm not that upset that these are empirical relations.

I'm going to skip way ahead past the detector stuff.

I think this is where we ended last time, where

we were talking about how do you detect dose

And I was outlining one proposed way that we're thinking of.

which changes color when it gets irradiated,

And as it moves from things like breathing or swallowing,

Or play nuclear operation, and try not to hit the sides.

And there's multiple implantation options for this.

We've thought about things like implanting a fiber optic

cable into the tumor, and then having a port

on the side of you that could do some in body spectrometry,

the F-center, and the spectrometer all in a chip

so you don't need to put a fiber optic port

And what we're doing next in this development

is nailing down what color change is given by what dose--

We've done the IP part, which is pretty cool.

As you can see with patent office at least

But it's neat that you need to know pretty much everything

you learned at MIT to pull off a project like this.

From the nuclear physics stuff, to the material science,

to the 22.071 electronics, to the medical stuff for biology,

In order to pull off an actual nuclear start

up project like this, you need everything you learn here.
