This is particularly challenging when orphan sources are hidden in scrap metal that shields their activity from the traditional detectors in the portals scanning incoming trucks. In order to address this issue, we present a wireless and compact SiPM-based gamma spectrometer compatible with strong magnetic fields (0.

For that purpose, a lipid--poly(2-isopropyl-2-oxazoline) (lipid--P(PrOx)) copolymer, self-assembling into thermosensitive micelles that phase-separate above a cloud point temperature of 38 °C, was blended in various proportions with commercial C--PEO. The latter was constituted of a hydrophobic saturated C chain and a hydrophilic poly(ethylene oxide) (PEO) block with varying polymerization degrees () and does not have any thermosensitive properties on the studied temperature range for any value of .
