You need purple eyes to pass the retina scan at the Rock Lab. As explained on the computer in the Research lab, it can fool the scans used for security.
Change them in the Research Lab. They will change back automatically.
Your eye colour must be purple
To enter the Rock lab, you need a keycard (dropped by Salerno when you find her) and purple eyes that you can get from the machine in the Research Lab.
When you find Salerno at the BioDome, she escapes through the airlock, and drops her keycard. If you have already turned your eye color to purple to beat the retina scan, you can follow her into the Rock lab.
There is an eye-color changing device just inside the Research Lab (north of the main base). Change yours temporarily to purple to fool the retina scan devices.
You cannot enter the Rock Lab without a key card. You don't get one until it is dropped at the Bio Dome by Commander Salerno. This is later in the quest. You will, however, need to go to the Research Station to recover the Locator Device. While there, use the eye color changer to make your eyes purple. This will let you pass the retina scan.
you need to click the eye scanner but make sure the mouse is out of the way.(;
You get the keycard when you follow Salerno to the BioDome. As she escapes, she drops the card by the airlock. You will chase her in the rover to the Rock lab, but you also have to have purple eyes to fool the retina scan. You get them when you are at the Research Lab (upper right by the airlock). To find Salerno, you have to get the tracking device from the Infirmary.
They scan your boarding pass because, after 9/11, you cannot go through security to the gate area unless you have a boarding pass.
The Rock Lab is the last of the three sites you visit on the Moon. To enter you need purple eyes (to fool the retina scan) and a keycard (which only Cdr. Salerno has). Your first stop should be the Research lab, where you can change your eye color and find the tracking device that will locate Salerno. To enter the Infirmary, squash yourself down with the pressure chamber. The locator will lead you to the BioDome, where Salerno is hiding. She escapes but drops her keycard. Chase her in the rover to the Rock lab and go inside.
Assuming you are asking what does the "p" stand for in Plasma and other digital televisions in the resolution such as 1080p vs. 1080i. The 'p' stands for "progessive scan" and the 'i' stands for "Interlaced". In a progressive scan each line is displayed sequentially from top to bottom. An interlaced scan displays every othe line in one pass then the other lines in a second pass.
The castle at Loch Ness is only a false front, and you can't go inside. In fact, it is likely that many players will never see while completing the quest. Most of it cannot be seen unless you climb on it. During the island preview, you could pass by it to use the binocular viewer to scan the loch, but that is unnecessary in the actual game.
No, you cannot pass radiation to others after having a nuclear scan. The radioactive substances used in these scans typically have short half-lives, meaning they decay quickly and do not remain in the body for long. After the procedure, any residual radiation is usually minimal and does not pose a risk to others. Your healthcare provider will give specific instructions on safety precautions to follow post-scan.
