Total tissue water responded as predicted by van't Hoff's osmotic relation to H2O?diluted seawater but was not clearly affected by the admixture of seawater with isosmotic MgSO4, suggesting that this solution may act as an isotonic medium.
Disturbance of symmetry results in a net electron current; a pulse of electromagnetic radiation is emitted which is strongest in directions per- pendicular to the net current.
Alpha radiation is the weakest. It can be stopped by a piece of paper and posses no threat to any human tissue. Beta radiation is strong, but still not lethal. It can be stopped by most clothing or fabrics. Gamma radiation is the strongest. It can only be stopped by lead.
