Reason For These High Detections

I actually look after the Caloundra local live monitoring station.

These very high detection's in this video up to 5000 CPM are equipment malfunction events. The monitoring software is computer based. One problem with this is if the computer locks up it can cause the software to show very high Counts Per Minute (CMP) very quickly. It is not a gradual increase, but almost instant.

When this happens I have to restart the computer and restart the monitoring software to get everything working properly.

Reason For The High Counts Per Minute

This local live monitoring station also uses a very sensitive SBT-10 pancake probe as the sensor. This probe it is much more sensitive than the Geiger counter tubes found in a lot of Geiger counters.

For instance a GammaScout Geiger counter would average around 12 CMP in this local environment, whereas this probe would average around 120 CPM.

Below is an explanation.

Important Notes:

Various live radiation monitoring station networks operate Geiger Counters or other detection equipment, that can have different sensitivities. Meaning, two  different Geiger counter models using different Geiger counter tubes placed at the same location would show different counts per minute (CPM).  One could show 12 cpm, while an another 120 cpm.  If they used a scintillator for detection purposes, which is even a more sensitive Gamma radiation detector, it could be in the thousands of counts per minute. Monitoring station counts per minute measurement all depends on the type of detection equipment the monitoring station is using.
uSv/hr or uRem/hr measurements are a way of defining human exposure dose rates independent of Counts Per Minute (CPM) equipment sensitivities.
You can only compare  detections of a  monitoring station against it's average background for that location. If it usually averaged around 12 cpm, 0.10 uSv/hr or 10uRem/hr at that particular location, this would be considered the average background level at that location. It may not be unusual to get a very brief detection three times this. If it stayed 3x or more background for any length of time, then something more serious is possibly happening.

Every circumstance is different so this is only meant as a general overview.
All monitoring systems are subject to malfunctions at times. Two or more monitoring stations in close proximity indicating an increase in background level is more statistically an indication of a genuine event.

The chart screen shot below is from the Caloundra Australia monitoring station, from the 1st December to the 2nd December 2018.

This significant spike in background radiation level occurred just after midnight on the 2nd December.

Note: The chart vertical axis is in nSv/hr, so divide by a 1,000 to get uSv/hr. The peak is close to 0.375 uSv/hr, Which is around three times the average background for this location.

There where major fires burning North of here at the time.

This Nullschool wind map below shows the wind direction and particulate overlay at the time. The green dot on the map marks the approximate location of the detection.

Was a fire the source of this detection or something else?

I have detected some more significant local background spikes.

The wind maps below show that during each detection the surface wind was coming off the Pacific Ocean. In each instance upper atmosphere high pressure system air was being draw down into low pressure systems.

Also at times during some of these detection's, the planetary Kp index levels were at near or zero levels. This means at the time there was very low solar wind levels and potentially much higher cosmic ray activity, pointing to a possible cosmic ray source.

This evidence points to these two possibilities for these recent significant spikes in local background,

A. Upper atmosphere contamination being drawn down to the surface by local weather conditions.

B. Cosmic ray bursts being detected.
