But not all radiation is equal. Electromagnetic Radiation  read more…

A new gel-based nanosensor for radiation dose monitoring can be used on skin and is relatively inexpensive.

Arizona State University researchers (in collaboration with Banner MD Anderson Cancer Center) have discovered a biocompatible cost-effective hydrogel that can be used to monitor therapeutic doses of ionizing radiation by becoming more pink with increasing radiation exposure. This picture shows a circle of hydrogel that was irradiated on the left half, which is slightly pink; whereas the right half of the gel is not irradiated and remains colorless. read more…
