Abstract EN
Plastic nuclear track detectors are widely used to register tracks of alpha particles emitted from radon gas nuclei and radioactive daughter nuclei.
Eye glasses, finger rings, necklaces and many other accessories intimately accompany most people.
The eyeglasses may modify the surface distribution of alpha particle pass spots just behind them.
There may be some effects due to the earth's magnetic field on the motion of the charged alpha particle emitters (radon ions).
In metallic frames of the eyeglasses, the earth's magnetic field and charged radio-ions enforce free electrons to move setting electric current, which reduces the magnetic field at the frame.
Being weak at the frame and stronger on both sides away, the magnetic field lines may form a magnetic trap of some charged radio-ions in the air.
The polymer Solid State Nuclear Track Detector (SSNTD) CR-39 which is a polyalyl diglycol carbonate is used to register alpha particles behind the eyeglasses obstacles.
Remarkable decrease in alpha track density was noticed in CR-39 registration due both to glass and magnetic screening.
The obtained results call for more studies on all metallic tools used or possessed in mines and non-ventilated underground cavities.
