Radium-226 (226 Ra) is the longest-lived isotope of radium, with a half-life of 1600 years. ... and its decay products can present serious health hazards.
It consisted of triple-distilled water containing at a minimum 1 microcurie (37 kBq) each of the radium-226 and 228 isotopes. The time of Radithor and radioactive elixirs ended in 1932, with the premature death of one of its most fervent users, Eben Byers, an American golfer. This history led to the strengthening of regulatory control of ...
An additional hospitalization in June 1996 was later recognized as having been caused by radiation exposure. An investigation in October 1997 found a number of sources throughout and around the property, including 200 radium-226 coated gun sights. The primary and most active source, a metal cylinder containing cesium-137 with an estimated dose ...

At least 12 nuclear isomers have been reported, the most stable of which is radium-205m with a half-life between 130~230 milliseconds; this is still shorter than twenty-four ground-state radium isotopes. [2] 226 Ra is the most stable isotope of radium and is the last isotope in the (4 n + 2) decay chain of uranium-238 with a half-life of over a ...
All EU countries are required to ensure that the activity concentrations of radium-226, thorium-232 and potassium-40 in construction products which be of concern from a radiation protection point of view, are determined and the resulting radiation exposure assessed before they are placed on the market.
Radioactive bone seekers are particular health risks as they irradiate surrounding tissue, though this can be useful for radiotherapy, such as in the case of radium-223. [ 2 ] [ 4 ] Stable bone seekers can also be harmful: excessive strontium absorption has been linked with increased levels of rickets .
The use of tubulars in the production process that are NORM contaminated does not cause a health hazard if the scale is inside the tubulars and the tubulars remain downhole. Enhanced concentrations of the radium 226 and 228 and the daughter products such as lead-210 may also occur in sludge that accumulates in oilfield pits, tanks and lagoons ...
