Radioactive dating disproved

Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on.

The various decay products, (sometimes referred to as “progeny” or “daughters”) form a series starting at uranium-238.

After several more alpha and beta decays, the series ends with the stable isotope lead-206.

Uranium-238 emits alpha particles which are less penetrating than other forms of radiation, and weak gamma rays As long as it remains outside the body, uranium poses little health hazard (mainly from the gamma-rays).

Moreover, it reacts readily with moisture, releasing highly toxic hydrofluoric acid.

Conversion and enrichment facilities have had a number of accidents involving uranium hexafluoride. military to fabricate armor-piercing conventional weapons and tank armor plating.

Uranium is also chemically toxic at high concentrations and can cause damage to internal organs, notably the kidneys.The principal goals of federal regulations are to limit the seepage of radionuclides and heavy metals into groundwater and reduce emissions of radon-222 to the air. Mandatory standards for decommissioning nuclear facilities including conversion and enrichment facilities are only now being developed by the U. Moreover, the half-lives of the principal radioactive components of mill tailings, thorium-230 and radium-226 are long, being about 75,000 years and 1,600 years respectively.The most serious health hazard associated with uranium mining is lung cancer due to inhaling uranium decay products.
