What is an isotope of strontium that has 52 neutrons?
Sr-90.
Is strontium radioactive?
Nearly 100% of all strontium found in nature is not radioactive. There are traces of radioactive strontium-90 found in nature, but only traces. Like all elements, strontium has radioactive synthetic isotopes.
How much neutrons does strontium 90 have?
Number of Neutrons = Mass number - atomic number = 90 - 38 = 52
What type of radiation is given off by strontium 90?
It emits Beta radiation.
What is the LD50 of strontium-90?
The LD50/50 (50% mortality in 50 days) for strontium-90 in rats is estimated to be around 2.5 to 3 microcuries per gram of body mass. I do not know if that translates linearly to humans.
How is strontium-90 produced?
is strotium-90 a solid liquid or gas
What is an isotope of strontium that has 52 neutrons?
Sr-90.
How many electrons are there in one atom of Strontium-90?
38
What is the product of a beta emission from strontium-90?
Yttrium-90 "the slash is important"
If 3.0 grams of strontium-90 in a rock sample remained in 1989 approximately how many grams of strontium-90 were present in the original rock example in 1933?
From the fact that Strontium-90 has a half-life of approximately 28 years, the amount remaining in 1933 would be 3.0 x 2^2 = 12.0 g.
Which type of cancer does radioactive Strontium-90 cause?
skin cancer

How long will it take until only 25 percent of the strontium-90 remains?
56
