First, the facts:

1. Radioactive contamination of the clothes with beta emitters

--- Quote ---Was there any contamination of the objects you are researching?
Answer: As stated in the conclusion, there is a contamination of radioactive substances (substance) by the beta emitters of individual, selectable areas of clothing, sent samples.

2. Strontium 90 is a common beta emiter

--- Quote ---"Strontium-90 is a commonly used beta emitter used in industrial sources. [...]It is also used as a thermal power source in radioisotope thermoelectric generator power packs"

3. Strontium 90 has been used in the Soviet Union for radioisotope devices


--- Quote ---Strontium-90 has been used by the Soviet Union in terrestrial RTGs. 90Sr decays by β emission, with minor γ emission. While its half life of 28.8 years is much shorter than that of 238Pu, it also has a lower decay energy with a power density of 0.46 watts per gram.[16] Because the energy output is lower it reaches lower temperatures than 238Pu, which results in lower RTG efficiency. 90Sr is a high yield waste product of nuclear fission and is available in large quantities at a low price.[16]

Abandoned Soviet Nuclear Batteries Found and Recovered in Georgia"
Two encased but unshielded sources of strontium-90, found near Georgia's northern border with the breakaway republic of Abkhazia late last year were safely recovered and transported to a temporary storage facility on Sunday.

Now, the theory:

Kolevatov is a nuclear physics student(4). He is involved in developing Radioisotope heater units (or maybe Radioisotope battery) based on Strontium 90, an isotope used in the Soviet Union(3). He brings with him this experimental device (6).
During the group last night, they didn't assembled the stove(not enough firewood, strong wind etc). Instead, they tried to use Kolevatov's device. Something goes terribly wrong with this device, (maybe small explosion) gasses, steam etc are emitted. They got scared, they cut the tent for the gasses (and for them) to come out as quickly as possible (or the tent was ripped by the blast). They know that the emissions are radioactive and everything inside the tent is contaminated, so they could not use anything that was exposed to radiation (clothes, shoes etc). They decide to go as far as they can from the contaminated area. What happens next is their fight for survival ... running barefoot, climbing in the trees for firewood, falling, making fire etc Maybe they were also suffering from radiation sickness, making the fight for survival harder.

What happened with the device?  Probably the secret services, army etc took it and cleaned the site before sending be the search teams, as I could not find any information in the case files about it. As the site remained radioactive, they closed the public access in the area for the next years (I remember I've read somewhere on this forum that they've closed the area for the next years) .


Star man:
It's an interesting idea.  It would only take an incident where the device was damaged and the material to leak out to induce the team to evacuate the tent.  But why go over a mile down the slope?  Maybe because they knew they had to find an alternative shelter?

You are in the middle of the night, barely clothed, the temperature is very low, with very strong wind... you cannot take the clothes or anything inside the tent as it is contaminated... maybe the device in the tent is still emitting radioactive gasses etc... What to do? First you need to start a fire. Where you can find firewood? In the forest of course. Also the wind speed is lower.

OK, so until now, my theory proposed an explanation for half of the mystery, which is why they left the tent without taking anything with them.
Next, I propose an explanation for the next mysteries : why the victims at the cedar are undressed, and why the victims in the ravine are dressed but inside the water, clothes radioactive.

My hypothesis is the following: the ravine is a setup of the "cleaning" team.
All of the hikers died under the cedar, around the fire.
Some of them because of the injuries caused by falling from the cedar, some of them by freezing... maybe by radiation exposure.
All of them had contaminated clothes, but the cleaning team had to make somehow the radioactivity disappear, as taking/replacing their clothes would raise too many question marks.
What was the easiest and obvious method at the site? Put the clothes under running water. So they undressed some of the hikers and put their clothes on the others, and after this they submerged them in the water, hoping that until the spring will come, the water will wash away the radioactive particles from the clothes. That's why they've suspended the search for the hikers in the ravine until may.

Still need to find an explanation for the hikers found between the tent and the cedar.

Monika:
But why would they make it so complicated? Why did not they just put them in closed coffins. And they found them in May because they were deep in the snow and in March the probe did not get to them.
And rely on the fact that the radioactivity will be washed out with the water is naive and unreliable method.
However, it is strange that the Investigator ever thought to test the body for radioactivity. Perhaps ihe was motivated by the fact that he noticed the burning ends of the trees near to the fire and ravine and began to have some suspicion. But it does not explain why the detector was with him? Does he usually wear it in his pocket???dunno1
Otherwise, I'm glad that someone still finds some new aspect that we can deal with. Thank you.

If any such device was found and it was considered to have been the cause of all the Dyatlov Groups demise then why would the Authorities want to cover it up. It would have been much better for them to simply say that a piece of equipment had malfunctioned. Its highly unlikely that any such Instrument was used by the Group. And what about those very unusual injuries to some of the Group  !  ?
