Radiation
Give your text an unhealthy glow.

|
| STEP 1 |
Start a new image and add your text, assuming white text on black background. Center the text and make sure you have a decent margine around it for the rays to go.

|
| STEP 2 |
| With the lower, white text layer selected, apply a Polar Coordinate conversion. Go to Filter>Distort>Polar Coordinates... Accept that the layer will be rasterized. Set it to convert from Polar to Rectangular. |
 |
|
| STEP 4 |
Since we want rays of light, we can achieve this effect with Wind. But because Wind only goes side to side, we need to rotate our canvas. Go to Image>Rotate Canvas>90 CW. |
 |
|
| STEP 4 |
Apply Filter>Stylize>Wind..., Method Wind, Direction From the Right. Apply it again, in the other direction. Rotate back like in step 3 and apply the Wind filter again in each direction.

|
| STEP 5 |
Apply Filter>Distort>Polar Coordinates... and convert from Rectangular to Polar.
|
 |
|
| STEP 6 |
Add a color balance adjustment layer (Layer>New Adjustment Layer>Color Balance...) and adjust to emphasize green.

|
And there you have it, the final version is easily cropped out. You may
want to try blurring the layer a little, though I like the sharp
rays in this case.
