Radio (Radioactivity)
Radio, the aspect of radioactivity, is a GTNH extension compound made from Potentia and Lux. One point costs 4 primal points to synthesize from scratch.
Recipe
Combine one point of each component at the research table to get one point of Radio. Counting all the way down to primals, a single point takes 4 primal points:
That total is the number the solver shows as craft cost when it places Radio in an empty cell.
What Radio connects to
Radio links to 2 aspects in this library (see the connection rule): its two components.
| Neighbor | Why it connects | Craft cost |
|---|---|---|
| Lux | Component of Radio | 2 |
| Potentia | Component of Radio | 2 |
No compound in this library is built from Radio, so its only neighbors are its own components. A fixed Radio on a note has to be approached through Potentia or Lux.
When Radio is printed on your note and you only need to leave it, Lux is the cheapest first step at cost 2.
Reaching Radio from each primal
These are the shortest valid chains in this dataset, using base and GTNH extension aspects. Where several chains tie on length, the one with the cheapest in-between aspects is listed. Cost counts only the aspects between the two ends, the cells you would have to fill.
| From | Chain | Cells to fill | Cost |
|---|---|---|---|
| Aer | Aer → Lux → Radio | 1 | 2 |
| Terra | Terra → Vitreus → Ordo → Potentia → Radio | 3 | 5 |
| Ignis | Ignis → Lux → Radio | 1 | 2 |
| Aqua | Aqua → Tempestas → Aer → Lux → Radio | 3 | 5 |
| Ordo | Ordo → Potentia → Radio | 1 | 2 |
| Perditio | Perditio → Gelum → Ignis → Lux → Radio | 3 | 5 |
A real note also has geometry: the chain has to fit the free hexes between your endpoints. If the gap is longer than the chain, pad it by stepping back and forth between two aspects that connect, or let the solver find a layout that fits.
Data source
Radio is in the GTNH extension group. Its default commonness is 46 out of 100, an editable estimate used by the Common ranking. The component pair was compared with GTNewHorizons GregTech aspect registration. The recipe table covers every component pair and the version limits.
