(b) Any employee who, prior to June 7, 1937, has contracted silicosis or asbestosis but is not disabled therefrom may, by August 6, 1937, file with the industrial board a request for permission to waive full compensation on account of disability or death resulting from silicosis or asbestosis, or any direct result thereof, supported by medical evidence satisfactory to the industrial board that he has actually contracted silicosis or asbestosis but is not disabled therefrom.

(c) If the industrial board shall approve a waiver filed under subsection (b), the compensation payable for such resulting disability or death of such employee, after further exposure in the employment of any employer shall be fifty percent (50%) of the compensation which but for such waiver would have been payable by any such employer.
