I have attached my Radiacode 101, to Dji Mavic Air 2 and sent it 500m high up. The units of measurnment are in uSv/h, at start it was 0.09uSv/h but that gradully got lower and lower. at 300m it was reading 0.03uSv/h, however after hitting 500m mark the radiacode 101 was reading 0.01uSv/h, this is the lowest reading I have gotten anywhere. To me what I think is happening is that as the levels stabilise to a certain degree in the height dimentional proportion of cosmogentic radioactivity then the levels of measurnment will get higher I was expecting this as above 1500m thats when reading are starting to get high, I will explain more about this for you guys. Cosmogenic Radioactivity is the Bombardment of the atmosphere by intense high energetic particle radiation (electrons, protons, and heavy elements) produced and accelerated by the magnetic field of the sun (solar activity cycle) and by distant cataclysmic events such as supernovae. The radiation is low as the green house gas layers of the earth atmosphere stops the radiation from hitting us however if you higher the radiation will hit you as it has low distance to travel. Cosmic rays cover a wide energy range, depending on the source (sun to distant supernova). The cosmic rays cause spallation effects in the atmosphere generating a secondary radiation flux of high energetic and often radioactive particles. Initial composition changes by spallation reactions generating a high flux of energetic secondary hadronic and elementary particles, the air shower. The earth atmosphere is not a constant entity, but subject to changes due to geo-chemical processes and developments, radioactive decay induced emissions such as Argon and Helium, and cosmic ray induced reaction processes. The earth magnetic field generated by the rotating Fe-Ni earth core dynamo provides a magnetic shield that deflects most of the positively charged cosmic ray particles and protects Earth from too high a cosmogenic dose!The danger is primarily for astronauts traveling in interplanetary space.
