The element radium was discovered by Marie Curie and her husband in 1898. By the 1950s, radium had become an ubiquitous element. Over 2 million radium clocks were sold, companies hired women to paint radium watches, and doctors sold radium water. At the time, radium was considered a miracle element because of its unique ability to glow in the dark. Thus, people naively associated it with healing properties.
Though it has been over 50 years since radium was widely used in consumer products, its effects have not completely disappeared. Radium poisoning remains a modern concern because of the element’s particularly long radioactive half-life, allowing it to remain in the environment for thousands of years. Although radium is no longer added to everyday products intentionally, people are still exposed to it through contaminated soil, groundwater, and older objects containing radium.
One of the biggest concerns of radium poisoning is contamination in drinking water. Radium isotopes occur naturally in certain rocks and soils, and dissolve into groundwater as water moves underground. Private wells are especially crucial to monitor because they are not always regulated by the same routine testing as public water systems. Long-term consumption of water contaminated with radium is detrimental because the radioactive particles accumulate in the bones, increasing the risk of bone cancer and other health problems. Unlike some contaminants, radium cannot be detected by its taste, smell, or appearance, making frequent testing essential.
Another modern source of exposure comes from abandoned industrial sites and former radium-processing facilities. Some historic buildings and properties may still contain radioactive paint on the walls from decades of industrial activity. Radium antiques also pose a risk to the public of mishandled. While an intact radium object is usually low risk when left undisturbed, its radioactive paint can become dangerous if it flakes apart or is inhaled or ingested.
The health consequences of radium exposure are particularly concerning because they do not appear instantly. Rather, symptoms appear over a period of time. When radium enters the body, it behaves similarly to calcium, allowing it to settle in bones and teeth. As it decays, it releases radiation that damages surrounding cells and DNA. Prolonged exposure can lead to bone cancer, leukemia, and other serious illnesses.
Fortunately, modern science has made it much easier to identify and prevent radium poisoning. Environmental testing can detect radioactive contamination in water and soil, while specialized filtration systems can remove radium from drinking water. Government agencies also regulate radioactive materials and establish safety standards to reduce public exposure. However, these protections are not universal, and communities with contaminated groundwater or limited access to testing may remain at risk.
Although the dangerous ignorance of the early twentieth century has largely disappeared, the effects radium left behind continue to affect the modern world. The tragedy of the radium girls and the widespread use of radioactive products serve as reminders of what can happen when scientific discoveries are embraced before their risks are fully understood. Radium’s history demonstrates that the consequences of unsafe scientific practices can last far longer than the products themselves.
