A method is described for checking film and film products for the presence of microdefects passing through the film. The method does not involve a positive gas pressure inside the product, and the effect of gaseous diffusion through the product is eliminated. This is brought about by the use of the radioactive inert gas thoron (/sup 220/Rn/sub 86/) which has a short half-life (T = 54.5 sec). The possibility of creating a highly sensitive device for monitoring the hermetic sealing of films and film products, which is free from radiation hazard, is shown.
