Once within the bone, Ra-223 emits alpha radiation that can destroy tumor cells within a 100-micron distance. This approach has been in use since 2013 to treat prostate cancer which has metastasized to the bone. [32] Radionuclides infused into the circulation are able to reach sites that are accessible to blood vessels.
Alpha radiation is a nuclear phenomenon in which a heavy radionuclide emits an energetic alpha particle (consisting of two protons and two neutrons) and transmutes to a different radionuclide. The emitted alpha particle has a range in tissue of only 40-90 microns, which minimizes collateral damage when used for treatment purposes.
Shielding: Sources of radiation can be shielded with solid or liquid material, which absorbs the energy of the radiation. The term 'biological shield' is used for absorbing material placed around a nuclear reactor, or other source of radiation, to reduce the radiation to a level safe for humans.
Targeted alpha-particle therapy (or TAT) is an in-development method of targeted radionuclide therapy of various cancers. It employs radioactive substances which undergo alpha decay to treat diseased tissue at close proximity. [1] It has the potential to provide highly targeted treatment, especially to microscopic tumour cells.
Alpha radiation has a very short range in tissues compared to beta or gamma radiation: around 2–10 cells. This reduces damage to surrounding healthy tissues, producing an even more localized effect than the beta-emitter strontium-89, also used to treat bone cancer. [17] Taking account of its preferential uptake by bone and the alpha particles ...
The largest natural contributor to public radiation dose is radon, a naturally occurring, radioactive gas found in soil and rock. [10] If the gas is inhaled, some of the radon particles may attach to the inner lining of the lung. These particles continue to decay, emitting alpha particles, which can damage cells in the lung tissue. [11]
Now, the team is curious to see whether this triple complex behind Deinococcus’ antioxidant exists in cells of other organisms, and if so, if they could be responsible for radiation-resistance ...
In theory BNCT is a highly selective type of radiation therapy that can target tumor cells without causing radiation damage to the adjacent normal cells and tissues. Doses up to 60–70 grays (Gy) can be delivered to the tumor cells in one or two applications compared to 6–7 weeks for conventional fractionated external beam photon irradiation.
