Extending Conditional Formatting in Google Sheets Using Dynamic Date Calls. Google Sheets, the spreadsheet tool that's part of the Google Apps productivity suite, lets users format cells based on certain conditions, including the date contained in a cell and how far away that date is from the present.
The Geiger counter, is an instrument used for measuring ionizing radiation used widely in such applications as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.eiger counters are widely used to detect gamma radiation, and for this the windowless tube is used. However, efficiency is generally low due to the poor interaction of gamma rays compared with alpha and beta particles.
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body.It was the first electrical measuring instrument. type of electroscope is also used in the quartz fiber radiation dosimeter. Electroscopes were used by the Austrian scientist Victor Hess in the discovery of cosmic rays. Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force.
