Which risk increases when a millimeter wave scanner's frequency is increased while maintaining constant power?

💡 Explanation

When frequency increases at constant power in a millimeter wave scanner, the electromagnetic wave's wavelength shortens, but total radiated energy remains the same, leading to increased photon energy and reduced penetration due to higher absorption rates. Therefore penetration depth decreases, rather than the others which improve or depend on external factors.
