Gold Radioactive: Isotopes, Applications and Effects

Gold is a shiny metal that is renowned for its beauty and value. However, not many people know that among the numerous isotopes of gold, there is a group of radioactive isotopes. In this article, we look at radioactive isotopes of gold, their medical uses, and potential environmental impacts.

Radioactive isotopes of gold have mass numbers ranging from 187 to 203 and varying half-lives ranging from as little as 2 seconds to a long 31,016 years. One of the most famous radioactive isotopes of gold is 198Au. This isotope is used in medicine, especially in radioisotope diagnostics and radiation therapy.

The 198Au isotope is used in the form of colloidal solutions, which are introduced into the patient’s body for the diagnosis of tumors and other diseases. Radioactive gold particles emit gamma radiation, which can be detected and recorded by special devices. This allows doctors to obtain detailed information about the patient's condition and accurately determine the location and nature of the tumor.

In addition, the 198Au isotope is used in radiation therapy. Gold particles irradiated with gamma radiation can be directed to specific areas of the body, where they destroy malignant cells. This is one of the cancer-fighting methods and can be especially effective in treating head and neck tumors.

However, it should be noted that radioactive isotopes of gold require careful handling and control. Their use must be strictly regulated and supervised by specialists in accordance with international safety standards. This not only guarantees the effectiveness of the procedures, but also minimizes possible risks to patient health and the environment.

The impact of radioactive gold isotopes on the environment also requires attention. Residues and waste containing radioactive gold particles must be properly disposed of to prevent environmental contamination and minimize potential risks to people and the ecosystem.

In conclusion, radioactive isotopes of gold, in particular 198Au, represent an important tool in medicine for radioisotope diagnostics and radiotherapy. However, their use must be controlled and carried out in a safe manner. Careful management of radioactive materials and proper waste disposal are key to minimizing potential risks.

Although radioactive isotopes of gold have their uses in medicine, it is important to note that their use should only be done under the supervision and prescription of qualified professionals. Self-medication or misuse of radioactive materials can have serious health consequences.

In general, radioactive isotopes of gold, in particular 198Au, are important tools in medicine for the diagnosis and treatment of tumors. Their use requires strict control and compliance with safety measures. Proper use and management of radioactive materials reduces risks and ensures the safety of patients, medical personnel and the environment.

Radioactivity of gold

Gold is an element with relatively high linear solidification shrinkage and therefore has a limited range of stable isotopic combinations. It can have atomic numbers 60-121. All these numbers are numbers for filling electron shells, and only 2 are completely filled. One stable atom of gold has a nuclide with a mass number of 742,231,068 (i.e. 1) and an atomic number of 50. It is an isotope of chromium, which has largely been replaced by gold plating. [1]

Other isotopes of gold are radioactive. The half-life of its longest-lived isotope (197Au) is 2.69×10^10 years.[2] This half-life is much longer than the existence of the universe and makes gold a unique metal in some aspects. Its ability to remain virtually unchanged even over millions of years has led to its role in the financial system in which we use it for our currency in the form of coins and bullion.

The remaining isotopes eventually decay through spontaneous α- decay
