This question is like asking how much smoking is harmful. There is no exact answer. Damage begins immediately. More exposure equals more damage. And this is exactly the problem with radon. It doesn't kill directly like, say, poison from a venomous reptile. The radioactive inert gas has a short half-life, and, when breathed in at measureable concentrations even below the recommended limit, some radon undergoes decay in the lungs. This irradiates surrounding tissue. The radioactive daughters of radon will also cause damage when they decay inside the body. The recommended limit of radon contamination in air is 4pCi/l (4 picocuries/litre of air). Even at this level and a bit lower, a wise homeowner would immediately get a consultation and seriously consider an option to deploy radon mitigation technology to reduce the level even more.
There are 1000 milliradians (mrad) in one radian (rad).
To convert RPM to rad/s, multiply the RPM value by 2π/60. This is because one revolution is equal to 2π radians, and there are 60 seconds in a minute. So the formula is: angular velocity in rad/s = (RPM) * (2π/60).
A rad is a unit of absorbed radiation dose, but it is not commonly used anymore. The International System of Units now uses the gray (Gy) as the standard unit for absorbed radiation dose. 1 rad is equal to 0.01 gray.
Carbon-14 is not considered dangerous to human health in typical exposure levels. It is a naturally occurring radioactive isotope found in small amounts in the environment and in our bodies. The low energy of its radiation makes it unlikely to cause harm.
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
I am not sure the question you are to ask, but there are many things that are hazardous and dangerous to human health.

The unit that measures radiation damage to human tissue is the Sievert (Sv). It takes into account the type of radiation, the amount of radiation absorbed, and the sensitivity of the tissue being exposed.
rad 12 - 3 rad 3rad 12 = rad(4*3) = rad (4) * rad(3) = 2 rad 32 rad 3 - 3 rad 3= - rad 3
There are many things that are poisonous to humans. Curare is one. Botulism is another.
rad stands for Royal Academy of Dance, which is a ballet company that offers exams and a ballet course in many countries worldwide
There are 3 syllables. Rad-i-ance.
1 rad = 57.3°
There are many dangerous animals that can harm a human. The most obvious ones are the larger ones such as lions and tigers. However, smaller animals such as stray dogs can also be dangerous.
No, pure water is not dangerous for human consumption. In fact, it is essential for maintaining good health and hydration.
