Radioactive fertilizer and the nuclear industry

About radioactive fertilizer and the nuclear industry.

A lot of the phosphate used for fertilizer comes from Florida where the phosphate ore is mined. That ore is contaminated with uranium and its decay products, especially radium. Radium disintegrates to produce radon gas Radon-222) and this builds up in an enclosed space, without adequate ventiliation, reaching an “equilibrium” in about one month.

That’s why Florida was the first “hot spot” that alerted the US government to the major public health hazard posed by radon, which is estimated to kill about 20-30 thousand Americans every year. Every atom of radon comes from the disintegration of a radium atom, and in turn, every atom of radium started out as an atom of uranium.

Radioactive quilibrium means #becquerels of radium = #becquerels of radon. One becquerel being one disintegration per second. In a simiar way, if pure radon gas is in an enclosed container, it will reach equilibrium with its four short-lived decay products in a couple of hours – so the radioactivity in the container is about five times greater than it was originally, as all the short-lived decay products have attained roughly the same level of radioactivity as the radon.

When this radioactive fertilizer is used on tobacco crops, the radon from the soil and the fertilizer builds up under the thick canopy of tobacco leaves and hangs there for a time (radon being 7-8 times heavier than air). The radon atoms disintegrate to produce four airborne solid short lived decay products – polonium-218, bismuth-214, lead-214, polonium-214, all of which decay into lead-210 and polonium-210. [Note: the last two nuclides never reach equilibrium, unlike the first four.]

These radon decay products stick to the resinous (sticky) hairs on the undersides of the tobacco leaves and when the tobacco is harvested these radioactive materials are harvested along with the tobacco. By the time the tobacco is cured, rolled, and packaged, small quantities of lead-210 (22-year half-life) and its immediate successor polonium-210 are left in the tobacco/cigarettes for the unwitting smoker (or second-hand-smoke inhaler) to encounter.

When the cigarette is lit and the smoker draws on it, the temperature at the tip increases dramatically and it vaporizes the lead-210 and polonium-210 which is inhaled deep into the lungs, where polonium-210 sticks to and attacks the sensitive lung tissue with its very energetic alpha particles.

Polonium-210 is a very damaging radionuclide which Los Alamos Labs reckons is about 250 billion time more toxic than hydrogen cyanide. (It’s what was used to murder Alexander Litvenenko in London at the “request” of Putin who was openly criticized by Litvenenko).

Polonium-210 adds greatly to the cancer-causing characteristic of the tobacco residues lodged in the lung, making cigarettes smoke significantly more carcinogenic than it would otherwise be. (When the smoker is not inhaling, the lead-210/polonium-210 is wafted into the second-hand cigarette smoke as a respirable aerosol to endanger the health of those within sniffing distance,)

Inside the lung, some of the inhaled polonium-210 crosses the blood-air barrier end enters the bloodstream. Being solid, it attaches to pre-existing plaque build-up in the arteries of the smoker, usually near the arterial valves, where the alpha particle bombardment causes fibrosis of the arterial wall and valve, thus exacerbating the plaque build-up and increasing the restriction of blood flow, thereby contributing substantially to the incidence of heart attacks and strokes among smokers because of the alpha emitting polonium-210 in the plaque.

What you may not have heard is that voluminous sand-like radioactive waste from the uranium industry, called “raffinate” (leftovers from uranium refining), is also sold as fertilizer on the open market without any warnings about the radioactive content. The justification for this nefarious practice seems to be, that since “natural” phosphate from Florids is used to make fertilizer, and it is clearly radioactive (due to the radium-radon chain), and since raffinate from a uranium refinery is not much higher in radioactive content, then what the heck, we (the uranium industry) may as well turn this sow’s ear into a silk purse by selling the radioactive raffinate waste as fertilizer.

Extensive radioactive contamination – involving uranium raffinate – of the homes, schools, roadways, ravines, and the public beach in the town of Port Hope (prior to 1985) – has led to a $2.6 billion radioactive environmental cleanup of the town (by the federal government) resulting in over a million cubic metres (about a million tonnes) of radioactibve waste to be stored for 500 years in a gigantic earthen mound just north of the town. The subsequent fate of the still-radioactive waste will be decided at that time.

This practice of selling raddinate as fertilizer goes on all the time from the world’s largest uranium refinery owned by Cameco, situated at Blind River on the north shore of Georgian Bay. The Blind RIver plant turns uranium mill concentrates from Saskatchewan, Australia and South Africa, called “yellowcake” (mostly U3O8), into a product called “uranium trioxide” UO3. At that point the raffinate is the waste product, contaminated with radium. That’s what’s sold for fertilizer.

The trioxide then goes to Port Hope Ontario, where it is chemically converted into UO2 (uranium dioxide) for domestic use, about 15% of the total, and into UF6 (uranium hexafluoride or “hex”) for export to enrichment plants outside of Canada where the concentration of U-235 is increased to the level required by the customer.

At the enrichment plant, the “hex” is turned into a gas at a fairly low temperature so that the heavier U-238 atoms can be separated from the lighter U-235 atoms, resulting in an enriched uranium product that goes out the front door while the voluminous discarded U-238 (called depleted uranium or “DU”) goes out the back door.

For low enrichment in light water nuclear power plants, about 85% of the refined uranium is discarded as depleted uranium. The DU has important military uses, and a few civilian uses, but for the most part DU is part of the radioactive legacy of the nuclear age wth a half-life of 4.5 billion years.

Besides using DU in conventional bullets, shells, missiles, tanks, et cetera, used in the former Yugoslavia and in other conflicts, resulting in a battlefield litters with radioactive waste, the military also uses DU as “target rods” in plutonium production reactors to breed plutonium for nuclear warheads. In addition, the military uses DU metal in almost all nuclear warheads as a way of significantly multiplying the explosive power of the warhead by a sizable factor. These weapons are called “fission-fusion-fission” weapons,

The first fission is from a small ball of plutonium (usually with a tritium “spark-plug” inside) whose sole purpose is to ignite the fusion reaction by raising it to a temperature of about 100 million degrees. When fusion occurs, extremely energetic neutrons are goven off which fission the U-238 that has been used for that exact purpose in the construction of the warhead. That third stage, the fission of U-238, provides the bulk of the explosive power and the lion’s share of the radioactive fallout.

It is a sad story from beginning to end.

And, to add to this tale of woe, Canada currently has about 220 million tonnes of radioactive waste (tailings) stored at or near the surface from uranium milling (the operation that produces yellowcake) along with about 167 million tonnes of radioactive “waste rock”. Yet the Canadian authorities and others routinely and unabashedly declare that nuclear power is a “clean” source of energy and for the most part, Canadian academic scientists and sientific bodies say not a peep to the contrary.
