"... Radon is a naturally occurring radioactive element, but it exists in such low concentrations in the air that it is less radioactive than peanut butter. ..."

claims

"...

Food contribues an average of 20 mrem/year, mostly from potassium-40, carbon-14, hydrogen-3, radium-226, and thorium-232.

• Beer= 390 pCi/liter
• Tap Water= 20 pCi/liter
• Milk= 1,400 pCi/liter
• Whiskey= 1,200 pCi/liter
• Brazil Nuts= 14 pCi/g
• Bananas= 3 pCi/g
• Flour= 0.14 pCi/g
• Peanuts 8 Peanut Butter= 0.12 pCi/g
• Tea= 0.40 pCi/g

..."

This means, to me, that controls need doing. Water alone, wire alone, in Cloud Chamber. Just to see.

• Good stuff DnG. Both entertaining and utile.

Here is an online calculator useful for our electrolytic endeavors:

Quoting JohnyFive:

"...

By the way the H2O-based cell was running at 0.2W from the beginning at around 50mA. Even at this low current water is very clearly evaporated - stream of water vapor off the cell is very noticeable.

..."

Running 0.2W and his mention of 4V agrees with his 50mA and tells us the cell resistance equals 80Ω.

Two tenths of a watt.

Four volts.

Fifty milliamp.

Eighty ohms.

Thank goodness for Georg Simon Ohm.

• I've been thinking about the chemistry in this simple-looking cell. It's only four elements in there, each 99+% pure. So maybe we can figure it out.

Here's one to start with: Nano Lithium Titanate (Li2TiO3 or Li4Ti5O12) is a battery electrode. This is a new technology, entering commercial use in Japanese EVs from Mitsubishi , Honda and more. The cell voltage is 2.4v

https://en.wikipedia.org/wiki/…%E2%80%93titanate_battery

If you measure the cell voltage after an experiment (with the power supply disconnected), you may see 2.4 volts. That would be a good clue to what's happening in the cell.

• RC Aircraft tech, nasty burn your house down type stuff but powerful ~

Ubiquitous PET can substitute for more expensive CR-39 for monitoring particle tracks.

Each type of plastic particle detector has its own etching method and is sensitive to particles in its own sensitivity range. For example, Cr39 is the most sensitive having a very wide detection range between .1MeV and 20 MeV. On the other hand, Polycarbonate is only sensitive to particles in the range between .3 MeV and 3 MeV.

The etching of this stuff and the analysis of the results is a process that requires the development of considerable expertise to avoid artifacts. This is nothing like amateur film-processing where mistakes are obvious because we are familair with photographs and what they should look like. Yes, it can be done but it isn't easy.

• Time to find a best practices document for track counting.

The skill that the experimenter applies in using the methods that he invents will reveal what underpins the processes that are being explored. For example, Holmlid has made huge contributions in exploring his field of interests because of the particle identification methods that he has invented and the skill that Holmlid employs in using those methods.

The experimenter should always be interested in uncovering new experimental methods and even inventing new methods. Galileo made a leap in the field of astronomy when he applied the telescope in looking at the planets.

• axil . Exactly- as you say Holmlid is very skilled. That was the point I was making. Your previous post kinda suggested that particle track analysis using etched plastics was no more difficult than taking a Polaroid.

• Some of the links above are not working for me. But, at least the first one is good. Thanks Nickec! It takes away that nagging question, "How am I going to measure muons?"

• Thanks for the effort Nickec. The first three work, somehow the last one generates a blank screen.

• It would be great if the Muon detector can be bought. There are only few people that can build it due to different reasons.
Anyway, how one can know that a Muons that are produced by LENR can be detected with this? Each detector is suitable always only for a certain energy range.

• johnyfive I am interested in replicating your experiment and publish my results here. I am ready to order parts to build two cosmicwatch detectors and the GC10 with an SBM20 and SBT 11A sensor. Have you considered trying a spark detector to verify for alpha particles?

You said a cloud chamber vapor will affect the paper substrate if you try to look for alphas but what about the other particles that can be seen or ruled out if you seal the paper substrate before putting it in the chamber?
