Hello Gents, Im interested in the Vromos Bay radiation ropic.
I can provide you with sand samples as many as needed as I live near by.

What does that mean???
The sand sample that I have - or at least about 100g of it - shows just about 11 CPS (125 CPS being the normal background in the room and 25 CPS being the normal background in my poor lead castle.

The spectrum (about 12h measurement with background extraction) gives out some nice Uranium products photopeaks...


So 11 CPS is totally OK???
Do you think there is danger on the beach and in the water at Vromos???
IMO there is no danger from gamma radiation at the beach. Also 0.20 uSv/h is the normal background in some neighbourhoods of Sofia. The sand itself has a higher percentage of copper, lead, cadmium, arsenic that came from the mine...and yeah, definitely some uranium in it as well. I would likely avoid having a picnic on it as fine dust from it may get into the food, blown by the wind. Personally, I would avoid the mussels they grow there either, not sure if it's a good idea to consume them.

Here is a VERY interesting read on VROMOS.

This is Vromos Beach



Is 0.20 MSv dangerous? How dangerous can it be??

Hi, it's 0,20 uSv NOT 0.2MSv !!

0,2uSv is safe level :-)

Natural gamma background in some places (say the town of Samokov) measures higher than that. If you are interested, you can find some places where background is much higher (1 uSv/h and even more) right next to Sofia, those are the now-closed-but-poorly-recultivated uranium mines near Seslavtsi or Gabra. There are even reports of mine material left along the road, even videos like that - https://www.youtube.com/watch?v=Sdr0FU7Hd2Q

People live nearby and from what I've read, it doesn't correlate to higher mortality rates or lower life expectancy. I wouldn't live there though.
