Recently, scientists in a certain country are trying to use particle accelerators to treat cancer  They put several tumor cell cultures, including glial cells, in a plexiglass vessel that simulates a human head  Then put this human head within the scope of the particle accelerators
Only tumor cells will die under the effect of the neutron beam.
 For the first time, scientists accumulate a sufficient amount of boron-10 in tumor cells, and then irradiate the tumor with a neutron beam to cause a nuclear reaction within the tumor cells, and the tumor cells die
