  • A couple things we can gather from these sources:

    1. Being near a banana is likely a much lower dosage. The BED article notes that eating a lot of bananas doesn’t give linear dosages, as the excess potassium is discarded. And if you’re not absorbing much radiation from it being literally inside you, I can’t imagine you’re getting much from having it further away (even at high quantities).
    2. According to the xkcd chart, we receive a yearly dosage of 390uSv from the potassium naturally in our bodies, and living in a stone, brick, or concrete building for a year results in only 70uSv. I’m not sure what the equivalent exposure would be for injecting those materials, but the picture I’m getting at this point is that external exposure to bananas would likely be less fatal than the sheer mass of what would be required to give a significant dose.


  • I’ve worked with lots of college students in my time. One thing I recommend to them is to pick classes based on the instructor, not based on the course content (something I wish someone had told me).

    A good instructor can make any topic engaging and enjoyable. And people have different preferences for how information is conveyed (for example, I gravitate toward instructors that use diagrams and other visual aids, it works best for me). So look around until you find someone that really clicks with you.

    The other thing that works for me is having some sort of end goal. I find it easier to stay engaged when I get to do something meaningful with what I’m learning.

    Out of curiosity, why do you want to learn more about these topics? Understanding your motivation might help to figure out something that works for you.
