A place to log background radiation, display charts and map, build, chat and create. radmon.org is for experimenters, enthusiasts and background radiation monitoring. You can send background radiation readings from a wide range of geiger counters, home built or kit built or some commercial counters. We welcome high CPM experiments, your own station news - if it interests you then it interests us!

A Geiger counter converts the ionization of gas within a Geiger-Mller tube into audible clicks or visual readings on a display. Each click signifies a detection event, effectively serving as an alert system for increasing radiation levels, allowing users to gauge their exposure time and act accordingly.

First measure your dose rate using a Geiger counter that reads out in mRhr. Understand that that dose rate includes both the radiation from the particular source of your focus that is emitting radioactivity, along with ever present background radiation. Then figure out the number of hours in a year that you are exposed to that dose rate.

Geiger Counter Chart. Just reading your Geiger counter is not enough to protect yourself from ionizing radiation. One needs to have complete knowledge of different levels of ionizing radiation and knowledge of which level is safe or normal and which level of ionizing radiation should be avoided. This level of ionizing radiation cannot cause

Geiger Counter Readings What are CPM units? CPM abbreviates Counts Per Minute and is a measure of radioactivity - a unit of measurement seen on some Geiger counters. Technically, quotIt is the number of atoms in a given quantity of radioactive material that are detected to have decayed in one minute.quot Most Geiger counters are calibrated to

What can a geiger counter teach us? What hidden secrets can a geiger counter reveal? How can a geiger counter protect us? Radiation Dose Chart. Note that there are different types of ionizing radiation the quotsievertquot unit quantifies the degree to which each type gamma rays, alpha particles, etc affects the body.

2. Do not get the Geiger counter wet. Use a sealed plastic bag to avoid moisture. 2. Avoid doing measurements in direct sunlight. 3. Avoid directly contact with the radioactive material. Use a sealed plastic bag if needed. 4. Turn off the unit when not in use. 5. Keep it in a protective pouch after use. -Background Safe Levels

Geiger Counter Interpretation Simplified I made this chart. Several other blogs have copied it nearly verbatim, and I am happy that others want to spread actionable information to protect people would have been nice to get a proper credit though. I had the chart translated to Japanese as I was sending a Geiger to Japan to help families

Depending on your location, your elevation or altitude, and your model of Geiger counter, this background radiation level might average anywhere from 5 to 60 CPM, and while background radiation or 2.5 times a Station's baseline readings. Thus, the quotAlert Levelquot for the National Radiation Map is the lesser of 100 CPM or 2.5
