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.
SURVEY INSTRUMENTS. Radiation survey instruments are used to detect potential radiation hazards, measure radiation intensities, monitor the effectiveness of shielding arrangements, and estimate exposure to personnel.There are two main categories of radiation monitoring devices: gas filled detectors and scintillation detectors.he kind of detector used is based on the intensity and the type of radiation field encountered. Scintillation detectors operate on the principle that certain materials scintillate or give off light when exposed to radiation. There are two major types of scintillation detectors, crystal and liquid.
