Miniature Radiation Shield

thingiverse

This design is for a compact Stevenson style radiation shield specifically tailored for temperature and/or humidity sensors. I modified another existing design (https://www.thingiverse.com/thing:3486326) to enhance its effectiveness at shielding sensors in the field, protecting them from excessive heating caused by solar radiation during daylight hours. The shield was designed to withstand harsh conditions in Brazil's Savannah, requiring it to be both resilient and effective. However, it is not perfect or fully tested, so exercise caution when using it for professional research purposes. If reliability of data matters, do not use this shield without first conducting thorough testing. To optimize the design, print the upper part with 80-100% infill, while the base piece can have a lower infill rate (40-50%). I used ASA material for printing due to its superior UV stability, ideal for long-term use in the Savannah. Despite this, lab tests revealed that the shield alone did not perform exceptionally well. To significantly improve performance, I attached a piece of foil to the top part of the upper component, which effectively reflected incident radiation and boosted test results. This design has yet to be tested in field conditions, only thoroughly tested in a controlled laboratory setting with the addition of foil.
