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.
A RIID is a radiation detector with the ability to analyze the energy spectrum of radiation, in order to identify the specific radioactive material (radionuclide) that is emitting the radiation. In addition, these devices can be used as survey instruments to locate radioactive material.ne particular meter, known as a teletector, is specifically designed to detect gamma and x-ray radiation. Named for its telescoping ability, this device can be extended to about 4 meters (13 feet) to measure very high dose rates without subjecting the user to unnecessary exposure.
