This is because when a neutron smacks an atom it may stick to it, turning that atom into another stable isotope or possibly a radionuclide. Unless you are either playing with Farnsworth Fusors or uranium reactors neutron radiation is not much of a concern, but nonetheless it is best shielded...
Disadvantage of GM survey meter is long dead time (100micro sec) and result in loss of 20% of counts in 100,000 cpm measurements. GM survey meters should not be used un high level radiation fields or when accurate exposure rates are required....
"Levels in the cpm range and millirad range are associated with a low-level risk to the medical personnel. Only in the rad/hr (Sv/hr) range would it be necessary to institute more stringent radiation protective procedures in non-life saving situations."Disaster Preparedness for Radiology Profes...

readings, but I'm going to stand outside counting for ten minutes every day — besides, I moved back to NY back in July 2011 and don't get to La Jolla as often as I used to today in 2014. If the CPM suddenly rose to 100, we'd have something, but that still would be safe. ...
