On the net. Atom. Electron. Behaviors of atoms and molecules.Chemical reaction.No effect to atoms.But radiation releted change is different.

Nucleus.Stable o9nes and unstable ones.Split of atom.Radiation.alpha rays,beta,and gamma rays.alpha and beta can be stopped by matters.

Gamma ray penetrate matter. Radioactive materials.cesium. cesium133,potassium39 are. Not radioactive. Not all the cesiums are radioactive.

What is Bq? 1Bq:radioactive material once breaks at 1sec,average. So, same Bq shows almost same amount of radiation.But not with weight.

Bq is a unit of, radiation amount. We mostly use Bq/kg, som.etimes Bq/Body. Caractaristics of radioactive materials.

Natural radioactive materials;K40,Radon222.artificially made ones;cesium137,plutonium.Energy behavir is same.EnergyStrengh are bit different

About WholeBodyCounter. Human have 60bq/kg radioactive K;possium.All Beta ray accumulated by body.Cannot check it. Gamma ray penetrate some

WBC checks the penetrated gamma ray from the human body. Helth effect to human body. External exposure/internal expos6ure.

Sv. mSv. Unit Shows about the damages to vhuman body. Effective dose/year. External effective dose is checked by dose meter.

0.25SV decrase of white blood cell. 1SV:cause nausea.10SV. DNA.radiation can cut DNA. But need to know cut DNA was often happen without rad

DNA cut and repair process is often occur in body. Someti7ms, they cannot repair DNA. Too much destruction of DNA causes death. But our ...

Cancers are incleasing.Data of 120,000ppl after atomic bomb.Propotional curve.100mSv.We don't knot much.In any case,Not much 'strong' effect

@hirokiharoki
Let's assume, 25% ppl die of canser.How much increase for 1000mSv? 25plus5. 100mSv, 10mSv. Average Japanese exposure 2.1mSv average.

West Japan is bit higher than east. About internal exposure.Might image 'internal' is much fearful and dagerous. Wrong. Same damage with ..
