My #Radiascan701A #GeigerCounter died a while back. It acts normally, except it is insensitive to known-spicy objects. I finally got around to breaking the warranty sticker to peek inside. I measure around 230VDC across the GM tube, and it emitted a click when I touched the DMM leads to the contacts. Maybe the electronics are still working, but the tube lost vacuum?

#Ukrainian #President #Zelensky has said he will travel to #Turkey's capital to meet President #Erdogan & will be available for direct talks with #Russia’s #Putin in Istanbul on Thursday.

"We will do everything to ensure that this meeting takes place," he told reporters in a hastily-arranged briefing in #Kyiv

Zelensky vows to do everything to ensure direct talks with Putin in Turkey

Russia has not yet said who it will send to Istanbul on Thursday and has refused to respond to ultimatums.

Day 30 ☢️🥔🤓

#PeterDutton (#Liberal) has abandoned a planned press conference after trade union #protesters interrupted his appearance at a local football club.

#ArthurRorris, head of the #SouthCoastLabourCouncil, joined with two other union supporters wearing #hazmat suits and holding a fake #GeigerCounter in the back of Dutton’s media appearance at the #StGeorges Basin Dragons #JuniorRugbyLeague club in #SanctuaryPoint.

Dutton was making a local announcement for the footy club and was preparing to hold a #PressConference when the three men entered the ground and called for the media’s attention. Standing in the area where Dutton was to hold his presser, the men played air raid sirens on a phone and held props including #nuclear ☢️ symbols.”

A reminder the LNP leader, Peter Dutton has no nuclear ☢️ policy. In fact no policies at all.

small update:

compared to the "official" local radiation measurement by Deutscher Wetterdienst my device showed slightly higher values.

@nocci found out that the conversion rate for the #J315 tube inside the #GeigerCounter housing had to be re-evaluated and fixed.

Now I am using 0.0065 and my values are down to the values the official station is recording.

Need advice: want to clean up some white and light yellow-ish deposits on a partially working circuit board that’s probably about 30 years old. Turns on but doesn’t register events from the Geiger-mueller tube.

My idea is to gently scrub where these deposits are with a new soft toothbrush and isopropyl alcohol and wipe/clean with cotton swabs.

Board measures Alpha, Beta, and Gamma radiation using a small LND-INC 712 tube. I’ve confirmed it’s getting 488V.

Good luck with that.

#JillStein isn't running for the #GreenParty. She's not even running because she wants to.

Stein's running so that, for the rest of her life, she doesn't have to #scan her #food with a #geigercounter before she knows if it's safe to eat.
