==== Kearny fallout meter ====
Commercially made [[Geiger counter]]s are expensive and require frequent calibration. It is possible to construct an [[electroscope#Gold-leaf electroscope|electrometer]]-type radiation meter called the [[Kearny fallout meter]], which does not require batteries or professional calibration, from properly-scaled plans with just a coffee can or pail, gypsum board, [[monofilament fishing line]], and aluminum foil.<ref name=A>{{cite book|last=Kearny|first=Cresson H|title=The KFM, A Homemade Yet Accurate and Dependable Fallout Meter|year=1978|publisher=Oak Ridge National Laboratory|location=Oak Ridge, TN|url=http://www.ornl.gov/~webworks/cppr/y2001/rpt/112538.pdf|url-status=dead|archive-url=https://web.archive.org/web/20040325094514/http://www.ornl.gov/~webworks/cppr/y2001/rpt/112538.pdf|archive-date=March 25, 2004|df=mdy-all}}</ref> Plans are freely available in the public domain in the reference ''Nuclear War Survival Skills'' by [[Cresson Kearny]].<ref name=NWSS11>{{cite book|last=Kearny|first=Cresson H|title=Nuclear War Survival Skills|year=1986|publisher=Oak Ridge National Laboratory|location=Oak Ridge, TN|isbn=0-942487-01-X|pages=95–100|url=http://www.oism.org/nwss/s73p921.htm}}</ref>
