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.
As far as the limits of radiation detection go, we can not only detect but measure the wavelength, frequency and energy of electromagnetic radiation (EMR). Long wavelength, low frequency EMR is radio that we listen to in the AM band. It is used to transmit over long Earth distances but is not much use for space communication.
