This article argues that metal detectors bestow an organizational stigma to schools.
Our numerical experiments demonstrate that these new detectors can lead to superior performance to several state-of-the-art detectors.
These detectors are highly radiation resistant and are good candidates for use in various application, where high efficiency, high resolution, gamma insensitive position sensitive neutron detectors are needed.
Because of its high spatial resolution and water equivalence, a diamond detector is found to be suitable as an alternative to other detectors used for small field dosimetry as there are photographic and photochromic film, TLDs, or water-equivalent scintillation detectors.
The outstanding properties of diamond, such as radiation hardness, high carrier mobility, high band gap and breakdown field, distinguish it as a good candidate for radiation detectors.
Simulation results show that the proposed detectors outperform the traditional detectors, especially in training-limited scenarios.
Numerical examples show that the two proposed detectors can provide better detection performance than existing detectors in some situations.
The quality of the images shows that these detectors are suitable for this purpose.
Based on these results the future prospects of such detectors are very encouraging.
Institutions concerned about their employees' and patrons' perceptions of safety should consider installing metal detectors in their EDs.

Further, these detectors are inexpensive to use and can be tuned to the specifics of the current business situations.
Progress in this field is encouraging, diamond detectors are already commercially available, and it is likely that diamond detectors will become the first choice within several niche market sectors.
Results show that it outperforms the conventional detectors.
The sensitivity of the system is practically preferable to that of metal detectors.
The insight given by this paper into metal detectors, will allow those not familiar with such instruments, a better understanding of their potential and limitations.
