Beta and Gamma Radiation in Madrid in Real Time

Why measure Beta and Gamma radiation?

There are few public sources of radiation data, so it seems interesting to have this information, given how dangerous it can be for health and the "obscurantism" that usually exists on this information. Can you trust the official sources?

Recently (April 2020) a forest fire in the area near Chernobyl has set off alarms by multiplying the usual radiation levels in the area by 16, dispersing a radioactive cloud throughout much of Europe (fortunately, it seems nothing serious) .

It is particularly reassuring for me to see a graph like this, with data collected by my own means at that time, which I know have not been tampered with: 

Geiger Home Radioactivity Counter

These radiation data are collected with a home-built geiger counter, so it should not be assumed to be correct.
