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.
The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter. Using a Typical Geiger-Mueller (GM) Counter to Survey. Get the GM counter and batteries from storage; prepare the instrument and determine background level.- Pay particular attention to hands, face and feet. -- Note that some GM instruments cannot detect alpha radiation and some low-energy beta radiation. Because alpha radiation is non-penetrating, it cannot be detected through even a thin film of water, blood, dirt, clothing, or through probe cover.
