I try to explain
In order to investigate in this direction, you must either be a specialist in this field or study reference books.
If we consider the source of radiation as the Kyshty accident, then the unloading of waste from a nuclear reactor consists
Let’s say that the emergency tank was loaded at the beginning of 1957, and the accident occurred in September 9 months later.
Share of waste
- 66% (33% at the time of the accident, ~8% after 3 years) - cerium-144
- 5% (~5% after 3 years) - strontium-90
- 3% - cesium-137
Since the half-life for cerium-144 is equal to the gestation period of 9 months, then after 36 months it is
after 27 months (May 1959) 1/8 × 66% = 8% remained in the form of the elements cerium-144 and praseodymium-144,
and 7/8 in the form of the substance neodymium 144, which has only alpha radioactivity, which occurs over 2300 trillion years and is barely perceptible

https://en.wikipedia.org/wiki/Caesium-137Caesium-137 has a half-life of about 30.05 years.[1] About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137mBa, Ba-137m). The remainder directly populates the ground state of 137Ba, which is stable. Barium-137m has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of 137Cs. Barium-137m decays to the ground state by emission of photons having energy 0.6617 MeV.
A total of 85.1% of 137Cs decay generates gamma ray emission in this manner.-------------
My gamma healing sensor, the battery of which I have not changed for 10 years, worked six months ago, now it turns on, but shows zeros.
Apparently the battery needs to be changed. But it is unlikely that such a problem existed in 1959.
Of the three popular accident products, only strontium90 fits the examination data.
it decays into yttrium-90 with an energy of 566 kiloelectronvolts (5.6 billion °C or kelvin),
and then within 64 hours the half-life of this yttrium into stable zirconium with energy
2.28 megaelectronvolts (thermal equivalent 22.8 billion °C)
(I find it difficult to convert these billions of degrees Celsius/Uelwyn into Fahrenheit, as the Americans like)
At most, Kolevatov’s heart counted 9 thousand decays.
If the cause of this is strontium-90, then it has only one gamma decay per 20 thousand decays.
Which may not be registered due to the sensitivity of the device.
Igor Pavloc (although it seems to me that the Partorg recently wrote it) may not have been aware of specific values.
But this variant with Strontium etc. cannot be the case with cesium-137 (or cesium-134),
for the device to register 0.5 MEV of radiation and at the same time not notice 1 MEV of gamma radiation is doubtful (a problem with the device, like mine).
Usually the opposite happens - devices do not notice beta radiation
those. the version of spontaneous natural pollution is eliminated.
Tritium is very weak beta-element. Another elements may be considered further.
