Radium Chemical Co. Needles and Tubes (ca. 1940s to 1950s)
Needles were intended to be inserted directly into the diseased tissue, whereas tubes were used for intracavity therapy, or superficial therapy wherein they were placed on the surface of the body. The text in the case is self-explanatory.

2023年7月6日 · Radium was fashioned into various sizes and types of sealed sources, many of which were called "needles" because of their shape. Radium needles and other forms were implanted into cancerous tumors to arrest the cancerous growth. Most uses of radium have been replaced by other radioactive materials or radiation generating devices.
In a general sense Dr. CLARK recommends letting the radium needles lie for 12 hours in the sarcomatic tumour tissiie with a distance of 12 mm. between the needles, and in carcinomatic tissue for 18 to 24 hours, assuming a distance between the needles of 25 mm. These tumours are now accessible to radium therapy.
Radium Needles to Radiotherapy: Cancer Treatment Evolution
Radium needles, very small tubes of radium salts, were implanted in the tumors to give radiation treatments. When radium was first used it proved to be efficient in treating cancer but long-term effects of the treatment were discovered to cause radiation sickness and burning of tissues.
INP is based on the IAEA recommendations fr te conditioning,, of low activity Radium needles, using activated carbon as te packing media to adsorb radon gas that may leak from the needles. In order to limit radiation to the fingers, distant tongues are used to perform manipulations on sources and capsules.
Brachytherapy - Radiology Key
2016年6月19日 · Brachytherapy is a method of treatment in which sealed radioactive sources are used to deliver radiation at a short distance by interstitial, intracavitary, or surface application. With this mode of therapy, a high radiation dose can be delivered locally to the tumor with rapid dose falloff in the surrounding normal tissue.

Brachytherapy is a type of therapeutic radiation used as an effective treatment for cancer. The method can also be used to treat tumors in many other body sites. Learn more about brachytherapy implants and how they work to irradiate cancerous cells inside the body.

New techniques in radium and radon therapy - ScienceDirect
New methods for the application of both radium and radon to the treatment of malignant disease are described. The basis of the radium technique consists in the preparation and use of a number of small independent radium cells which can be inserted as required into hollow sheath needles of appropriate length.
