They have had to reinforce and add material to the shore in the past to prevent too much becoming exposed. They only sorted it in the last few years by sifting the entire beach for particles!

​@@EddieTheH Thats natural ...due to the Granite... In the buildings and the underlying Geology.. Igneous rocks tend to be rich in metal ores ..radioactive elements... the other problem is Raydon gas getting trapped indoors as it rises up out of the rocks beneath ... Cornwall/Dartmoor has the same problem. Though igneous rocks dominate some areas like Bedfordshire also have hot spots due to clays that formed millions of years ago from the erosion of earlier igneous or volcanic rocks... radioactive isotopes can hang around for a very very long time.

The black sands are more than iron, use a magnet to separate the dark minerals between magnetic and non-magnetic. The non-magnetic minerals are probably zircon, a tough and heavy mineral that also can include thorium in the zircon crystal lattice, quite a bit sometimes. The abundant zircon minerals at the beach are probably a direct result of the erosion and transport of zircon, quartz and magnetite / hematite grains from the Sierra Nevada granitic batholith in the Sierra Nevada mountains, which contains abundant amounts of those minerals. Rivers transport them to the ocean and the wave action sorts the heavy minerals from the lighter, thus the band of dark sands. Winter storms, like the most recent in California tend to scour nearshore material and transport it to the beach, where it is sorted at the hightide wave. Placer deposits of gold on the beaches of Nome, Alaska, or placer titanium on the beaches south of Jacksonville, Florida are there for the same reason, erosion of large mountain ranges (Sierra Nevadas, Appalachians......) and transport to the sea, followed by concentration and transport by wave action nearshore and longshore. Also, zircons are nearly indestructible, they survive plate subduction and the melting of the rock around them, in fact growing larger, scrubbing more Zr and Th and U and Si from the magma.

As a former sand miner, I can tell you that most beaches have a high radioactive reading. Monazite (black sand) is the radioactive component. Thorium should be the radioactive source. When dredge runs, it’s digs through layers of different sands, then usually it settles close together because it is a much heavier material. If you fill a bucket with rutile, you can’t lift it, the bucket will break even half full.

Thank you, I appreciate you answering me. Am wondering if Fukushima could be part of the cause of the radioactivity in this video.

When Heike Kamerlingh Onnes finally liquefied helium for the first time in 1908, he did it with helium obtained from this material at painstaking laborious cost. His brother Onno was director of the Commercial Information Office in Amsterdam, which allowed him to obtain monazite sand from the British Monazite Mine in Shelby, North Carolina. The large quantity of thorium in the sand made it valuable for manufacturing thorium mantles, used to increase the efficiency of lighting from kerosene lamps, but the hard grains of sand also locked in the helium produced by most steps of the the well known long thorium decay chain. The liquefaction of helium opened the door to the discovery of superconductivity, then superfluidity, and most recently the Higgs field (the LHC is cooled with superfluid helium) which is of course ultimate reason why your sand feels so heavy. Everything is connected.

Beaches on the california coast that collect heavy sand during storms are the most radioactive, such as Fort Funston near SF. The radioactive mineral appears to be zircon but there are two different types. Under the microscope you can tell them apart, regular zircon grains are clear little crystals and the highly radioactive grains are more greenish and rounded looking. They are slightly more dense than regular zircon and can be separated by panning if you remove the magnetite and ilmenite with a magnet first. I concentrated a sample consisting of just a few grams of this supersand and it has an activity of around 1000cps on the radiacode, showing the thorium-232 peaks and possibly and little bit of uranium also.

The more of the non zircon sand you can remove, the higher the readings you can achieve. Some of the samples I have processed have been as high as 70% magnetite so that can be a big help. The ilmenite tends to be pretty abundant also and can be removed with a magnet but its a bit more work - I did it by dropping it past a large magnet (similar to an hourglass) and that way you can sort between the slightly magnetic grains and the nonmagnetic grains. From my testing, all the radioactivity is contained in the zircons, a little bit in the regular zircon and the bulk of it in the greenish radiation damaged grains. If you can get rid of the magnetic grains, you can just pan the remains to get down to the radioactive fraction. Usually there is a little bit of gold mixed in as well but the best ive seen is only about 1 ppm.@@RadioactiveDrew

I've been going to this beach since the '50's and it has been eroding into the sea for many years. It begins near the jetty and so the state replenishes the sands by pumping offshore sand onto the beach through those rusty pipes. So most of the area you checked, down to 20 feet or more, is from offshore sand. The Naval Weapons Station stores any and all naval weapons but does no production of nuclear materials. Further down the beach is the San Obispo Nuclear Power Station, long a symbol for the coastal cities, especially Hunting Beach. Then there has been some debris that washed ashore from Japan. But the rediation MOST likely comes from all the oil industry drilling and pumping along the coast and natural materials from the area.

My Grandmother had a house on Seal Beach in the mid 1960's. Back then, there were few houses on the beachside of the street because the shore line was right there; the houses on that side of the street were on pier pilings so the high tides and storm tides could wash under them. During storms the water would even cross the street and up to the houses on the opposite side of the street. In the late 1960's they started to pump sand out onto the beach - this took a couple of years. They extended the beach out at least 200 yards - maybe 300. Total trip dude! the pipe had to be 3 feet high, and they created a giant hill that ran the entire length of the shoreline. That hill was as tall as a house, and they then pushed the hill out even further. Seal Beach had one of the best breaks - a surfer's paradise for sure. I grew up with a pool in the backyard, so I could swim like a fish. My folks would not let me have a surfboard - I was too young, but body surfing was off the chain down there! In 1970 or 71 her house burnt down; we were all out to lunch and came home just in time to save a few things and watch it burn to the ground. Really sad too, GrandMa's house was deck-out to the 9's with beach stuff - SoCal was a great place to grow-up back then. One other note about back then; you could see 2 or 3 offshore oil rigs off of Long Beach out in the bay. When we came in off the beach, we had to check our feet for tar. We used Trichloroethylene 1.1.1 (I think) to clean the tar off our feet; it was some type of solvent that dissolved the tar, with a little rubbing. So, take that into consideration of your findings.

So far it seems like the thorium deposits aren’t correlated with oil wells. I say that because there are loads of wells that use to exist in Huntington Beach but I haven’t found the same thorium deposits. In Seal Beach / Sunset Beach there aren’t any old oil wells…at least looking at the records I’ve found. Living down by the beach can be quite an experience. I use to live in Costa Mesa for a couple years and always enjoyed going down to the Huntington Beach area to skate at the park. Sorry to hear about your grandmother’s house.

Several beaches in France and the Camargue are a little radioactive because there is thorium in very small grains. At first the researchers thought of a leak at the Tricastin nuclear power plant and the Pierrelatte reprocessing center, which are on the banks of the Rhône, which could have released radioactive products which ended up in the sea just towards the mouth of the Rhône. Other beaches near Cap D'Agde are slightly radioactive listed by the ASN and the IRSN.

Drew, very cool video! This could be tailings from all of the oil drilling activity in the early 20th century; a TH232 deposit deep underground. Perhaps, because of its higher specific gravity, the material could be early oil drilling mud (containing residual TH232) that was used to stabilize the bore holes. Please keep the videos coming!

The thorium could have totally come from the oil drilling. But it also might be from a natural deposit that is eroding into the ocean.

Would be interesting to learn what is in that sand. High thorium usually means lots of nice rare-earth minerals (commonly found in monazite sands). Ever tried concentrating or extracting the thorium? Just magnetically removing the iron would be a good start to the separation.

@@RadioactiveDrew Cool, I'll check it out.👍

A couple comments... First off, I own a 103, and it's the most fantastic detector built. I;ve actually given the company some ideas that they have implemented in the product, but I don't work for them (I'm not paid by them). But they are really nice and very receptive about their product. They are releasing a more sensitive version, the 103G on May 24th, 2024, so if you want to buy one you might want to hold out for that version. About 20 years ago I took a class offered by the Civil Defense organization for detecting radiation. It didn't cost anything, but you had to agree to provide the government with radiation readings if the country gets nuked. Not sure what infrastructure existed for me to supply this information, but I'm probably in yet another government database... And my amateur radio license wouldn't hurt in that case, if I did survive. All kind of like a science fiction movie to think about. Anyway, I don't know if the Civil Defense department still exists (probably part of Homeland Security now), but if the classes are still available it's definitely worth taking. I think I would have reported that hot spot to the city. I know it's not immediately dangerous to passers by. But, as I learned in the class, danger comes from 3 things: Time, Distance and Dose. The Dose is rather high, add time and distance to the equation and it could be a problem. If someone picked that particular spot and laid over it all day long soaking in the sun they would get a sunburn, but they would also get more radiation than they should. It's always best to receive as little radiation as possible. And the problem is, unless you have the equipment to measure it, you'll never know you are being exposed to it. Also, ingesting radioactive compounds can be bad because of the close distance and long duration (Time and Distance). Some things can't be helped, like potassium. But it doesn't hurt to avoid as much as possible. Especially when you are young.

Great video I never have heard of naturally radioactive sand. Everything you said makes sense though.

@RadioactiveDrew I'm just repeating the industry standard definition. Thorium was moved onto the beach where there was none before. Thorium is radioactive, and in spite of it being NORM, it represents a measurable albeit small hazard. If someone dumped radioactive sand on my driveway, I would consider it contaminated. My assessment is based on more than 40 years of dealing with radioactive materials including direct interactions with the Nuclear Regulatory Commission. I know what I'm talking about. Instead of being defensive, perhaps you should take this an opportunity to learn. I learn something watching all of your videos even though you were a novice up until recently. I'm not sure why you don't have a similarly open mind to input of others.

I used to work for a dredging company and when you started filming dredging equipment is when I got worried. Cutter suction, hopper, and and other form of hydraulic dredgers use density gauges that are semi-exposed to the moving material. Those metal and black, plastic pipes you filmed actually degrade very fast, especially when the material being dredged is rocky or sandy. There were two radiological related incident reports I had to fill out where the incident revolved around unsafe work performed near the destiny gauge. We had two different sources on our dredges. Cesium 137 salts and cobalt 69. My biggest fear was somehow losing that source or somehow exposing the casing to moving material. Not many dredge personal are even aware about how insanely dangerous those sources can be.
