## The Sounds of the Atoms

I made the recordings and the images seen in the video.

Sounds made using a GS1100A from GammaSpectacular.com, a Radiation Sensors SPA38 from SpectrumTechniques.com, sources from SpectrumTechniques.com (and other places), software from PRA

The gamma energies are detected by the NaI(Tl) detector and converted into pulses of electricity, proportionate to their energy (low energy, low voltage, high energy, high voltage). The spectrometer converted these to sound. The higher the energy, the higher the pitch of the sound.

Monazite, a Rare Earth Minerals rich mineral found in many parts of the world, from India, to Brazil.

This is my new Pentax Asahi Takumar 1:1.4/50mm lens… but it also happens to be radioactive! It contains Thorium 232.

## Uranium Glassware Shopping!

I journey to Fredericksburg VA to find uranium glassware to buy!

## (Radiation and Geiger Counters) How to Separate Alpha, Beta, Gamma

Tagged as , , , , , , , ,

Background 38 CPM
Total 19,262 CPM *
Beta+Gamma 14,116 CPM *
Gamma 1,392 cpm *

* values shown minus background (e.g. 19300 CPM total becomes 19,262 CPM after 38 CPM removed)

This is how we figure it out:

Alpha = Total – Beta+Gamma
Beta = Beta+Gamma – Gamma
Gamma = Gamma

We can replace the words for real values from above:
Alpha = (19262 CPM) – (14116 CPM) = 5146 CPM
Beta = (14116 CPM) – (1392 CPM) = 12724 CPM
Gamma = (1392 CPM) = 1392 CPM

The results sum back to the total, which helps us check our work:
Alpha + Beta + Gamma = 5146 CPM + 12724 CPM + 1392 CPM = 19262 CPM

Here’s that bit about the copper lol I added it for fun, but it is correct.
Sheilding HVL of Copper: 10.2 mm
Thickness of Sample: ~4mm
Most Common Energy of Gamma: 214Bi 609.31 keV at 44.8%
e^-log(2)4mm/10.2mm = 0.76199, where d/dx e^-((ln(2)/10.2mm)*x) = (4^((-2+x)/x) log(2))/x^2
