<title>Degradation of fast electrons energy and atomic hydrogen generation in an emission plume from atomic power stations</title>

Remote monitoring of emission activity level from NPP using radiofrequencies 1420, 1665, 1667 MHz in real time

“…In order to find power Q n which the electron radiates in the interval of wavelengths dn it is necessary to sum dn over all collisions. Assuming the diffusion to be isotropic, the electron deceleration time w10 À6 s and taking into account results presented in Kolotkov et al (2006), after summation we obtain the amount of energy from 0.1 to 2$10 À12 erg cm À3 emitted in the wavelength interval 844.7e4200 A.…”

“…As collisions of electrons with atoms occurs rarely (in comparison with the frequency of the radiated electromagnetic wave), it is possible to consider the consecutive collisions as independent, and the energy radiated at many collisions is simply the sum of the energies radiated by the separate collisions. As the act of scattering occurs very quickly in comparison with the period of the field oscillation, it is possible to write down the formula for the quantity of the bremsstrahlung electron energy in the frequency interval dn per second (Zel'dovich and Raizer, 1966;Kolotkov et al, 2006):…”

“…Further we analyzed potential reactions inducing to H and OH generation. Kolotkov et al (2006), where N e is a sum of energies of the ninth generation of electrons in 1 cm 3 of air; and E is an energy of electron, keV. These calculations were carried out using recurrence relation by SpencereFano formulas which defined probability of electron collisions in above-threshold region of energy (Spencer and Fano, 1954) and under these assigned conditions:…”

“…It is necessary to note that emissions from nuclear fuel cycle enterprises, including both NPP and RCP, differ in isotope composition (Kolobashkin and Rubcov, 1999). Necessity of taking into account many electron generations is because secondary, tertiary and further electrons have sufficient energies to ionize environment calling photochemical reactions in the atmosphere with appearance of radioactivity marker by which spontaneous emission is determined a radioactivity level of emission from NPP (Kolotkov et al, 2006). As an additional marker of radioactivity it is suggested to use hydroxyl spontaneously radiating (1665e1667 MHz) at the same frequency range as hydrogen atom.…”
