The novel design solution has demonstrated a detection area of 0.05m2, which is an increase of 335% over the previous design proposal. Additionally, the design was more compact than previous designs improving the portability. The novel design proved successful in measuring background radiation and locating a beta source emitter within the detection plane, demonstrating the feasibility of the modular design. Further conceptualised improvements leveraging AM design capabilities have decreased print time by 38% and material used by 36%, making the component more economically viable.

Accelerated lifetime testing was carried out to mimic the operating conditions of Lynkeos’ system. The first-ever characterisation of the response of Polyethylene Terephthalate Glycol (PETG) and Acrylonitrile Butadiene Styrene (ASA) to gamma radiation was carried out. The findings indicate that PETG exhibits excellent mechanical resistance to high-intensity gamma radiation. At an exposure of 0.75 MGy, PETG maintained 99.2% and 93% of its ultimate tensile strength and maximum strain, respectively.
