ISO 31-10と放射線量の単位・記号に関する解説

ISO 31-10ISO 80000-10放射能吸収線量
An illustration of the relative abilities of three different types of ionizing radiation to penetrate solid matter. Typical alpha particles (α) are stopped by a sheet of paper, while beta particles (β) are stopped by 3mm aluminum foil. Gamma radiation (γ) is dampened when it penetrates lead. Note caveats in the text about this simplified diagram.[clarification needed]

ポロニウム210の特性と危険性強力なアルファ線放出体の科学

ポロニウム210アルファ崩壊放射能ウラン系列
A quantity undergoing exponential decay. Larger decay constants make the quantity vanish much more rapidly. This plot shows decay for decay constant (λ) of 25, 5, 1, 1/5, and 1/25 for x from 0 to 5.
