Radioactivity Induced

Artificial radioactivity caused by nuclear reactions occurring during irradiation of stable nuclides.

When irradiated with neutrons, protons, deuterons and other particles, some stable nuclei can enter into nuclear reactions and turn into radioactive nuclei. This radioactivity is called induced radioactivity.

An example is the reaction of neutron capture by a phosphorus nucleus with the formation of the radioactive isotope phosphorus-31:

30P + n -> 31P

Another example is the reaction of proton bombardment of nitrogen-14 to produce the radioactive isotope oxygen-15:

14N + 1H -> 15O

Thus, induced radioactivity occurs when a substance is exposed to a stream of particles capable of causing nuclear reactions. It is artificial in nature and, after cessation of irradiation, gradually disappears as the resulting radioisotopes decay.

Artificially induced radioactivity. **In our world, nature is constantly struggling with human ambitions and production.** Food and various chemicals have long been produced that can be used both for the benefit and harm of humanity. In this article we will look at induced radioactivity.

- Contamination with radioactive substances occurs **due to emergencies in nuclear energy, during the purification of spent nuclear fuel, as well as during scientific research.** This leads to a negative impact on the environment and human lives.

Chemical manufacturing, research laboratories, and even medical facilities experience occasional, albeit unlikely, radioactive releases. These emissions **may be associated with the storage and transportation of radioactive substances, the use of faulty or damaged radioactive sources, emergency situations and other situations.** Each of us knows that radioactive substances are very dangerous for humans and especially for children. That is why they should only be used in specially equipped and protected rooms and places.

Radioactivity is a phenomenon in which radioactive decay is accompanied by radiation and the release of energy. However, there are also artificial P. (induced), caused by nuclear reactions. This phenomenon is called radio frequency induced P. One example of induced radio frequency method of monitoring the current state of a machine is an acoustic monitoring system consisting of two cameras and a transceiver. The connection is formed between two differently configured receivers in each camera. The signal signals from these receivers are sent to the tuner, which compares them and selects the one that indicates that the speakers are tuned. In case of any unusual sound, it is converted into an analog signal and sent to the central controller.

This tuning method may not be very useful for older pianos, as they may produce subtle sounds that will not show up clearly in the frequency response. Also, tuning when using this method may require significant effort from the machine owner to achieve optimal parameters under various operating conditions. On the other hand, using the induced radio frequency method will solve this problem and significantly simplify the tuning process and improve the sound quality of the piano. Therefore, it can be argued that the use of induced radio frequency methods in tuning musical instruments is a necessity, which allows improving the quality and reliability of control. In addition, such methods can significantly improve the accuracy of settings and eliminate the possibility of incorrect settings caused by human factors.
