!!!The most important aspects of safety!!!

Key things to reduce exposure:
1. Shielding
2. Time (of exposure)
3. Distance

Key things to keep safe:
1. Minimize exposure if possible.
2. Always wash hands and wear gloves.
3. Never allow inhalation or ingestion of dust from samples.
4. Keep samples away from children (anyone, actually) and only bring
5. Never store samples under your bed (not sure why they do, but apparently people do this lol)

Good books:
Introduction to Radioactive Minerals – Robert Lauf

Places to buy uranium:

(eBay and Amazon have some too, but be careful!)

CDV700 – VArious places (careful of bad units… may need repair and claibration)

Spectrum Techniques Universal Computer Spectrometer UCS30 – A Review and Overview

Tagged as , , , , , , , , , , , , , , , , , , , , , ,

A nice little unit, the UCS30 comes with 512, 1024, 2048, or 4096 channels. The unit has a built-in high voltage source and a pre-amplifier.

There are many great and wonderful scientific devices which we can obtain and use to understand our world. The most important things we can do in our lives are to learn all that we can and teach as much as possible to all who will listen.

The unit can be seen at http://spectrumtechniques.com/

Oh… and no, they didn’t ask or pay me to show off their unit. Unfortunately, I had to buy the unit myself 🙂

A quick demonstration of nuclear radiation. Just for fun and maybe even a little education. =)

7 Days Later – My Radiation Dose for Seven Days

Filed under Radiation, Science
Tagged as , , , , , , , , , , , , , ,

And so it came to pass…

I wore my Polimaster 1703MO-1B gamma spectroscopic dosimeter for seven days to find out what my dose was. Of course, I only detected photon radiation from 40 keV to 3.5 MeV, and only external sources.

My total dose was 14.52 uSv

Which wokrs out to:
2.07 uSv / day

0.0864 uSv/hr

757.11 uSv/year

I estimate that my actual dose is much greater, at perhaps 2.523 mSv, but that is based on supposition and no actual hard evidence. 🙂

Equations (simplified for quick and dirty use!!!)

  2 * (E keV)^2
___________________ = Compton Edge
  511 keV + 2(E keV)

                  2 * (E keV)^2
E keV – ________________ = Back Scatter peak
                  511 keV + 2(E keV)

(Tom’s opinion)
Best source for calibration: Cs137
Best detecttor type: NaI(Tl) 1″ or greater!
Best free MCA software: PRA 8
