Use of scintillation radiation detectors, in the range of visible and UV spectra, to be used to find undeclared radioactive material in routine inspections at borders, customs, street, military operations, etc. The idea of SDC Project is to use scintillating material sensitive to ionizing radiations coupled to normal CCD (charge-coupled device), CMOS (complementary metal-oxide-semiconductor) or any dedicated photodetectors. There are many scitillation radiaton detectors material sensitive to ionizing radiation, the most common are crystals but are expensive and need large photodetectors and a very big and heavy electronic chain to be esed. The scintillation radiation detectors I propose are composed of ceramic material as GADOX (Gadolinium Oxysulfide) doped with rare earths (like Eu, Ce, Tl...). This material have been tested in many labs of the world (including mine) with very good results. GADOX material is very cheap and effective to detect radioactive material. This material can be coupled directly to detectors sensitive to visible or UV light, such as CCD, CMOS or specialized photodetectors. many experiments have been ade with the CCD of the mobile pones with very good results.
The idea is to design and build a large detector composed of GADOX and CCD and to be tested in the space with the cosmic radiation. the reason for a large detector is to know the direction of the ionizing radiation (when two or more CCD detect at the same time, is to say, have a coincidence) and the energy of the particle; if the particle (coming from the radioactive material) has a lot of energy, then more volumen of GADOX detect will be crossed (more CCD, CMOS or sensitive photodector will see the light produces in the GADOX). When these photodetectors see the light coming from the GADOX, then an alarm signal will sound or will be visible with external warning lights. in the space there are a lot of ionizing radiation particles with different energies, this is the reason to test it.
Less than 3 cm x 3cm x 25 cm for the detector.
Also take into account the batteries for the photodetectors; size required 3cm x 8 cm x 2 cm.
And a Little electronic circuit to save the data of the experiment.
Yes, to find undeclared radioactive material in routine inspections. The undeclared radioactive material could be used in dirty bombs or any terrorist purpose.
2 or 3 batteries like the mobile phones.
The focused is the proper functioning of the batteries. I do not know if low temperaturas affect them.
Could be used a wire data transfer , or a Little bluetooth or radio circuit, or perhaps could be used a data storage memory. This experiment could be adapted to the cubesat conditions
This experiment could be adapted to the cubesat conditions
Is not required knowing the bus stability and attitude control of the cubesat.
None special paltform accomodation requirements are needed
