Medusa Explorations Groningen
Description
A better view of the soil by Medusa
Soil replenishment has taken place, e.g. as part of the reinforcement of the seawall of a Wadden Island. Sand dredgers have been there and sucked up sand far from the coast. Later, this sand was deposited just in front of the island's dunes. The question now arises: to what extent has the thickness of the sand layer in question increased? This question seems difficult to answer. Again, however, physics offers a solution. This is because the sand is slightly radioactive. It emits gamma rays. These can be measured using modern equipment from the Medusa company. And now the elevation of the seabed (planar) can be quantified. Indeed, an increase in the sand layer on the seabed will cause the gamma rays mentioned to become stronger.
Apart from using gamma radiation, at Medusa one also uses ground penetrating radar, measurements by acoustics, Research by measuring magnetism. As a result, Medusa is able to get a good picture of the soil:
Using the techniques mentioned, the company investigates foreign objects, rubble dumping sites, cable and pipe locations, among others. And the methods also lend themselves to investigation of archaeological remains, especially foundations.
The Board of the Department of Technical Physics hereby invites you to visit this particularly interesting company.
On 4 June, an employee of the R&D department will give an introduction. He will tell something about the techniques involved in this new form of soil research. This will be followed by a tour of the company where the new measuring instruments will be shown.
The meeting will conclude around 4 pm.
