The existing radiation marker generally comprises a bearing part and a marking rod fixedly arranged at the top of the bearing part. Of course, when the radiation pollution accident occurs, radiation pollution exists not only on land, but also in the air, because radiation source substances can fly in the air along with wind, and radiation 'diffusion' is realized in the air. To monitor radiation pollution in the air, the applicant has devised an air marker that can be flown to a designated monitoring point in the air of a radiation pollution area for marking.
