A consensus or society position rather than new primary data.
This is a narrative review synthesizing historical and contemporary evidence on radium's toxicology, medical mechanisms, and clinical applications. The source documents that radium's historical promotion as a therapeutic agent has been superseded by evidence of radiological toxicity, but notes that certain radium isotopes retain limited medical use in targeted cancer treatment when dose and safety are carefully managed.
Review. Populations exposed to radium through historical therapeutic use, occupational exposure, or contemporary targeted radionuclide therapy for specific cancers.
Radium is absorbed into the body and deposits in bone tissue similarly to calcium, with a proportion eliminated through feces and urine and remainder persisting in skeleton Chronic exposure to elevated radium levels is associated with hematological abnormalities, cataracts, dental and jaw damage, bone cancer, and increased mortality Severity and onset of adverse health effects are closely related to absorbed dose and duration of exposure
No quantitative data on dose-response relationships, incidence rates of adverse effects, or efficacy of contemporary radium-based therapies provided Chronic exposure to elevated radium levels is associated with hematological abnormalities, cataracts, dental and jaw damage, bone cancer, and increased mortality
Clinicians should be aware that while radium's historical use as a general health remedy caused documented harm, modern targeted radionuclide therapies for specific cancers may be appropriate when dosimetry, tissue tolerance, and re-irradiation risks are carefully assessed. Continued surveillance and regulatory frameworks remain essential for safe management of radium-containing materials.
A narrative review synthesizing historical and contemporary knowledge about radium's toxicology, medical applications, and safety considerations; informative for clinical practice and public health but not reporting original research evidence.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Following its discovery, radium was initially promoted as a therapeutic agent for a wide range of conditions, including skin disorders, allergies, visual problems, joint pain, and as a general health-enhancing remedy. However, subsequent research demonstrated its significant radiological toxicity and harmful effects on human health. Despite these risks, more than a century after its discovery, certain radium isotopes continue to have limited medical applications, particularly in the treatment of specific cancers. Following ingestion, radium is absorbed into the body and behaves similarly to calcium, resulting in its deposition in bone tissue. A proportion of absorbed radium is eliminated through feces and urine, while the remaining fraction may persist in the skeleton and contribute to long-term internal radiation exposure. The severity and onset of adverse health effects are closely related to the absorbed dose and duration of exposure. Chronic exposure to elevated radium levels has been associated with hematological abnormalities, cataracts, dental and jaw damage, bone cancer, and increased mortality. Advances in radiobiology, radiation protection, and personalized medicine continue to improve the safety and effectiveness of radiation-based treatments. Modern radiotherapy, including selected applications involving targeted radionuclide therapy, requires a detailed understanding of radiation dose distribution, biological responses, and patient-specific factors. The optimization of re-irradiation strategies remains an important clinical challenge that requires careful assessment of previous radiation exposure, tissue tolerance, and potential risks. Because radium exposure can occur through ingestion, inhalation, or dermal contact, continued monitoring, appropriate regulatory frameworks, and access to specialized analytical methods remain essential components of public health protection. International cooperation and strengthened surveillance programs are needed to ensure the safe management of radium-containing materials and minimize potential health risks.
