The advent of the environmental SEM (ESEM) has made possible the examination of uncoated and untreated specimen surfaces in the presence of a gaseous or liquid environment. However, the question arises as to what degree the examined surface remains unaffected by the action of the electron beam. It is reasonable to assume that the beam invariably affects all specimens but the type and degree of effect may be totally unimportant for one class of applications and totally unacceptable for another; yet, for a third class, it is imperative to know how our observations are modified by the presence of the beam. The aim of this report is to create an awareness of the need to initiate research work in various fields in order to determine the guiding rules of the limitations (or even advantages) due to irradiation.

Knock Out

It is well known that various electron beam induced effects can occur under high energy electron beam irradiation on the studied material in an electron microscope. It has been reported that under electron beam irradiation small metallic Ni particles can be reduced from the bulk NiO crystals and these Ni crystals are always in epitaxial relationship with the NiO substrate. These Ni particles may be formed by the preferential knock-out of oxygen atoms by the incident electrons and the subsequent aggregation of Ni atoms to form the nucleii. These nuclei will grow with further electron beam irradiation, forming the small Ni islands on the surface of the NiO crystals. Recently, we observed that not only does the reduction process occur on the NiO surface but also other kinds of interactions occur at the same time. First, large NiO crystals can be melted and flow away from the radiated area in an electron microscope. The process is radiation dose dependent.

Degradation Effect

Electron beam radiation effects of PET have been investigated. Microstructural changes in poly(ethylene terephthalate) subjected to electron beam irradiation at doses of 50kGy, 100kGy, 200kGy, 400kGy were investigated by Attenuated total reflectance infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) , Atomic force microscopy (AFM) and scanning electron microscopy (SEM). Irradiated samples showed a increase of crystallinity with a minimum at 200kGy, which is attributed to secondary crystal and then an decrease at further doses due to some degradation effect. The chemical structure and surface topography has only a slight change with irradiation.

Mycotoxins cause adverse effects on human health. Therefore, it is of the utmost importance to confront them, particularly in agriculture and food systems. Non-thermal plasma, electron beam radiation, and pulsed light are possible novel non-thermal technologies offering promising results in degrading mycotoxins with potential for practical applications. In this paper, the available publications are reviewed—some of them report efficiency of more than 90%, sometimes almost 100%. The mechanisms of action, advantages, efficacy, limitations, and undesirable effects are reviewed and discussed. The first foretastes of plasma and electron beam application in the industry are in the developing stages, while pulsed light has not been employed in large-scale application yet.
