2.Two units you should know
What are commonly used units?
Will you teach me about radiation and radioactivity units?
Let's discuss two commonly used units in detail.
Becquerel (Bq) and Sievert (Sv).
Bq
Becquerel
Unit of measure of the ability of a radioactive material to emit radiation
= intensity of radioactivity.
alpha rays
beta rays
X-rays, and gamma rays.
Radioactive material
Radiation includes alpha rays, beta rays, X-rays, and gamma rays.
Sv
Sievert
A unit of measurement of the effects of radiation exposure on humans.
human
Effects on the body are expressed in Sv.
Let's look at some situations where these two units are commonly used.
Bq
Becquerel
used per weight or area.
Bq/kg
Bq/cm2
Sv
Sievert
used per hour.
mSv/y
μSv/h
About Units
One thousandth of 1 Sv is 1 mSv and one thousandth of that is 1 μSv.
Even if the radioactive materials are different, if the numbers in sieverts are the same, the effects on the body are the same.
I want to know more about numbers and units.
Here's the point!
Bq
Becquerel
A unit of radioactivity strength
Sv
Sievert
A unit that measures the radiation dose received by humans
