A second site of radioactive contamination in the Kotlovka district of Moscow: detection, survey, notification to 911 and the police, and then the elimination of the dangerous radiation anomaly. This time, the gamma background level was only slightly exceeded, but the beta particle flux density was over 3,000 particles per square centimeter per minute, compared to the norm of 10–20. 0:01 - Introduction - A new site of radioactive contamination has been discovered near the old one. 0:45 - Survey of the hazardous site: the gamma background level is barely exceeded, but the beta particle flux density from the soil is enormous! Measurements were taken with three devices: the MKS-01SA1M, the MKS-15D, and the DRGB-01. 4:23 - Call to 911 and the fire and rescue service. 6:45 - Police arrive. 7:10 - Spectrum shows radium 226 and its daughter decay products. 7:35 AM - The rescue service arrived, but without a beta radiation meter... I had to call 911 again. 8:40 AM - I went to the police to file a report about the discovery of a dangerous area of ​​radioactive contamination. 9:35 AM - The next day, employees from the Radon Federal State Unitary Enterprise arrived and removed the top layer of soil contaminated with radioactive substances.
