Irradiation from internally deposited radionuclides induces malignant tumors. Ingested radionuclides accumulate in specific organs, which are irradiated over a lifelong period. Our aim is to elucidate why the development of malignant tumors requires long-term internal exposure, on the order of

Thorotrast was used as a contrast medium in clinical practice until the 1960s for outlining cerebral abscess cavities and ventricular cavities, and for angiography. Gliosarcomas, meningiomas, and schwannomas have been reported previously, as has Thorotrast-associated angiosarcoma, typically in the liver.
