“…The term radionuclide refers to or is tantamount to unstable nuclei. Cobalt-60 [13] can undergo radioactive decay due to its excess nuclear energy, which then results in the accumulation of stable daughter nuclide. Stable daughter nuclide denotes nuclides which have infinite mean lifetimes.…”

In this work, we provide a solution to a special case of Bateman equations using quan- tum calculus. However, we can derive such a solution because Bateman analysis is usually per- formed for the following cases:(i) the daughter nuclide is stable, i.e., λd = 0 assuming Nd(0) = 0; (ii) t1/2 (parent) < t1/2 (daughter); (iii) t1/2 (parent) > t1/2 (daughter); and (iv) t1/2 (parent) ≫ t1/2 (daughter). Ergo, we will only consider case (i) in this quantum-analysis. Moreover, we will perform a q-analysis on a set of miscellaneous quantum-values—provided q ∈ (0,1); a/k/a the superextensive or superadditive regime—using Tsallis functions; in particular, Tsallis q-logarithm.

“…In [7], an innovative scheme for producing 60 Со in CANDU6 reactors (Canada) was proposed, which makes it possible to triple the operating time compared to earlier production methods. However, the disadvantage of the new scheme is an increase in the maximum power of the channel and a decrease in the safety margin of the reactors, which in turn again leads to an increase in the cost of production of the final radionuclide.…”

This paper reports an alternative technique for producing a source of hard gamma radiation with the 60Со isotope for the proposed device for radioactive irradiation of birds, which is also innovative in providing for ornithological aircraft flight safety. However, the high cost of producing a 60Со radionuclide source with activity sufficient to irradiate bird pests with a lethal or sterilizing dose poses a serious challenge. A solution to the problem of reducing the cost of a 60Со radionuclide source can be an alternative technique of its production outside the reactor. The results are characterized by the following features and distinctive peculiarities that make it possible to solve the problem under study: – an irradiation device with the radioactive isotope 60Со causes a lethal or sterilizing effect. This is much more effective in ensuring ornithological safety of aircraft flights compared to known methods of scaring away birds of prey, but is harmless to humans; – the production of 60Со radionuclide for the irradiation installation is carried out by thermal diffusion heating, which significantly reduces the cost of the source compared to the well-known methods of its production in a reactor and accelerator. The results obtained could find practical application in the field of civil aviation for ornithological flight safety, subject to compliance with national and international legislation. In addition, the proposed technique of manufacturing a 60Со radionuclide source, in addition to aviation ornithology, may find application in other sectors of industry, economics, and agriculture
