Abstract:
A system and method for performing fractional resurfacing of a target area of skin using electromagnetic radiation are provided. An electromagnetic radiation is generated by an electromagnetic radiation source. The electromagnetic radiation is caused to be applied to a particular portion of a target area of skin. The electromagnetic radiation can be impeded from affecting another portion of the target area of the skin by a mask. Alternatively, the electromagnetic radiation may be applied to portions of the target area of the skin, other than the particular portion.
Abstract:
A wall or ceiling lining system with a required level of X-ray transmission resistance includes a plurality of X-ray transmission resistant wallboards 2, 3 with at least one joint 4 or gap between an adjacent two or more of said X-ray transmission resistant wallboards. Each of the joints or gaps is provided with a wallboard jointing material 8 including at least 30 per cent by weight of barium sulphate or an equivalent. A method of lining a wall or ceiling with a wall or ceiling lining system having a required level of resistance to the transmission of X-rays is also disclosed.
