No, it cannot be used like lead. Radiation shielding of high intensity photons (X-rays, gamma, ...) works by attenuation. Attenuation is (almost) purely a function of how much material you have in between and how dense it is. You can block alpha with anything, beta with any metal surface. I'm wondering if it's purely just nonsense as I suspect or if there's some aspect I'm not considering. I mean it does work against beta, so it's useful in that you don't need an additional surface, but that's pretty stretching.
