Fill in the blank. 1. you want to be shielded from all three types of nuclear radiation. if you find shielding that blocks radiation, then it will most likely also block the other two types. 2. when nuclear radiation enters the tube of a geiger counter, it the atoms of the gas contained in the tube. 3. the particles that make up protons and neutrons and are thought to be basic units of matter are

1.  If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type deposits all energy into a single atom)
3 The particles that make up protons and neutrons and are thought to be basic units of matter are quarks.

The answer is !
