New cover for dosimeter BR-9B. Compared to the original cover, the following has been changed:
1) The height of the lid is lower compared to the original, the device has become more compact
2) The dosimeter is converted to lithium (you will need a 102050 battery and a charging board)
3) The geiger counter tube is now closer to the lid, and there are also holes in the lid to improve sensitivity to "beta radiation"
