For next week, there are just two short readings I'd like you to look at. Both deal with describing "ionizing radiation" sources, and introduce the concept of a "radiation dose." Both are also "propaganda" in the sense of being educational materials produced by the nuclear industry. As you read them, do you see any places where the authors are trying to persuade you of anything?
1) Radiation dose chart and information brochure from the American Nuclear Society
2) Ionizing Radiation brochure from the Australian Nuclear Science and Technology Organization
Note that there are special units for measuring ionizing radiation doses, and that these two publications use different versions of them. The ANS brochure uses "millirem" and the ANSTO brochure uses "microseiverts." We will untangle these terms in class, but they are two units for measuring the same thing, much like how feet and meters are both units for length.

The Radiation Facts article is trying to persuade the public that very little radiation is received from power plants. It shows many different ways that people receive radiation. People are exposed to far more mrems of radiation from many of these ways than from power plants.
