Radionuclide profiles 0101 for radionuclides with unstable atomic nuclides can automatically release rays and decay into another nuclide. 02 atoms are an integral part of the atom and consist of protons and neutrons. Atoms of nuclides with the same proton number and different neutron numbers are called isotopes and isotopes are called nuclides. Radionuclides are defined as radionuclides such as 01 alpha, beta, gamma, by type of radioactivity. 02 natural radionuclides and artificial radionuclides by source. 03 radionuclides with long half-life, short half-life and ultra-short half-life, classified as half-life. The classification industry detects and controls radionuclides for non-destructive detection, thickness measurement, composition analysis, etc. Medical diagnostics and treatments such as x-ray, ct, mri, and radioactive drugs for cancer treatment. Scientific research is used to study atomic nuclear structures, explore the origins of the universe, etc. The degradation mode of radionuclides applied to radionuclides02 releases the alpha decay of helium atoms as radionuclides release a helium atom core (composed of two protons and two neutrons) and transform it into a nuclear reaction of another element. In this decay, the atomic sequence is increased by 2 and the mass is reduced by 4. The concluding remarks describe in detail the release of the alpha decay wrap-up words, either electronic or positive, describing in detail the beta decay as a nuclear reaction by radionuclides that release an electronic or positive electron and transform it into another element. In this decay, a neutron in the atomic core is transformed into a proton and electronics are released. Beta decay summation releases gamma rays detailing gamma decay as a nuclear reaction by radionuclides that release gamma rays (high energy photons) and transform them into another element. During this decay, the number of atomic sequences and protons remained the same, but the mass was reduced. Gamma decay releases a proton, an electron and a neutron decay as a nuclear reaction to the transformation of a neutron into a proton, an electron and a neutron. In this decay, the atomic number is increased by 1 and the mass number remains unchanged. The neutron decay describes in detail the length of time taken to halve the nuclide decay pattern of nuclide 03. Defines $t {1/2}=frac{ln2} $, of which $$λ is an decay constant. The formula used to describe the decay rate of radionuclides is one of the important parameters of radionuclides. Application of half-life 123 radioactive activity decreases exponentially over time. Description of $a(t) = a 0e^-λt}, where $a(t) is the activity after time of $t, $a 0 is the initial activity and $aλ is the decay constant. The formula is used to predict the decay of radionuclides and to calculate the activity at different time points. Applying an index decay pattern formula of $a=frac{n}, of which $n 0 is the number of atoms at the initial moment, $λ is the decay constant and $t$ is the time. Applications are used to assess the potential impact of radionuclides on the environment and organisms, as well as applications in fields such as medicine, industry and scientific research. The method is calculated on the basis of the number of rays or energy from measured radionuclides, combined with parameters such as their half-life. The safety and protection of radionuclides for the calculation of activity requires professional training in the nature and operation of radionuclides. Experiments are conducted strictly in accordance with operational protocols to avoid accidents. When handling radionuclides, personal protective gear such as glasses, gloves, etc. Should be worn. Upon completion of the experiment, radioactive waste should be properly disposed of in accordance with the regulations. The safety protocols for radionuclides are well-established, such as screens, ventilation cabinets, etc. Radionuclides are regularly monitored to ensure that their concentrations meet national standards. Operators should undergo periodic health checks to detect and address possible radiation damage in a timely manner. Special protective measures, such as wearing protective clothing and respirators, should be taken in specific cases. The protection measures for radionuclides develop a sound safety management system and define the duties and operating protocols of personnel at all levels. To strengthen the safe management of radionuclide storage and use sites and ensure their compliance with relevant regulations and standards. Periodic safety assessments of radionuclides are conducted to detect and remove safety hazards in a timely manner. Strengthen collaboration with the relevant departments to jointly secure and protect radionuclides. The application of radionuclide decay patterns to the safe management of radionuclides 05 uses radionuclide-marked visual agents, such as a positive electronic launch fault scan (pet) and a single photo-launch computer fault scan (spect), to detect tumours, heart diseases and other diseases without incident. Radionuclide diagnosis serves the purpose of inhibiting the growth of tumours or killing cancer cells by introducing radionuclides such as iodine-131 and thorium-89 for internal tumour exposure treatment. The application of radionuclide treatment in the medical field to soil pollution monitoring of 0102 uses radionuclide trace techniques to track the transport and spread of pollutants in the soil and provide a basis for soil restoration and remediation. By measuring radionuclide concentrations in water bodies, water bodies can be judged to be affected by sources of pollution such as industrial wastewater, discharges from nuclear facilities, etc. Application of radionuclide tracer technology in environmental monitoring to enable accurate detection of hydrocarbons
