“…This property (low fading rate) shows high stability of produced free radicals at CFQ material by electron irradiation at room temperature. Such behavior has also been previously observed by other researchers in various materials used for ESR dosimetry [3,5,6,29]. The sudden signal decrease immediately after irradiation also suggests an allowable suitable time after irradiation for dose measurement.…”

“…This method and ENDOR are uniquely suited to study the effects of ionizing radiation [2]. Nowadays, it is a high-ranking method for dose measurement [3][4][5]. ESR dosimetry with alanine is applied for industrial uses, and is formally accepted by IAEA as a secondary standard for high dose and transfer dosimetry [6][7][8][9].…”

Polycrystalline ammonium dithionate has been examined for its radiation response in the low dose range (< 5 Gy) using EPR technique. The-radical ion was detected as a single EPR line with a peak-to-peak derivative width of ca. 0.44 mT in irradiated samples and its intensity was found to vary linearly with dose. At equal and moderate settings of microwave power and modulation amplitude ammonium dithionate was at least 7 times more sensitive than L-alanine which is the most common EPR dosimeter standard. Pulse experiments were performed on the powder samples to obtain the longitudinal relaxation time. These and microwave saturation experiments served to indicate the optimal microwave power to be applied during measurements as an EPR dosimeter for best sensitivity of this material. It is thus claimed that ammonium dithionate has excellent potential to become an EPR dosimeter with a low limit of the measurable dose for cases where tissue equivalence is not required or can be corrected for.3

“…The basic physical concepts of ESR are analogous to those of nuclear magnetic resonance (NMR), but these are electron spins that are excited instead of spins of atomic nuclei [20]. The magnetic field splits the spins into two groups (aligned and opposite with the magnetic field).…”

The paper presents analyses of current research projects connected with explosive material sensors. Sensors are described assigned to X and γ radiation, optical radiation sensors, as well as detectors applied in gas chromatography, electrochemical and chemical sensors. Furthermore, neutron techniques and magnetic resonance devices were analyzed. Special attention was drawn to optoelectronic sensors of explosive devices.
