| actinism |
Actinism is a property of radiation (particularly solar radiation) that leads to the production of photochemical effects. Actinism is derived from Greek with the meaning a radiant force. The word actinism seems to be used particularly in terms of imaging technology especially photography although it is used in medical literature for photo-biochemical effects such as a sunburn or radiation exposure from ultraviolet rays and in chemistry for containers that protect from photo-degradation. ...

| actinide |
The actinide series encompasses the 14 chemical elements that lie between thorium and lawrencium on the periodic table with atomic numbers 90 - 103 inclusive. The actinide series is named after actinium, and this element is often included in the series by convention. All actinides are f-block elements except lawrencium. A strict correlation between periodic table blocks and chemical series would include actinium in the series and place lawrencium in the transition metals. ...
