Ingesting any solid body such as plastic bulbs can be harmful, but the liquid in the bulbs is completely non-toxic. The aluminum disk reduces the propensity of the bulbs to mutually resonate. The bulbs' exterior is made of plastic. They are shockproof and can fall to the ground without suffering any damage as long as they are not submitted to any sort of mechanical pressure. We are not aware of any other products which have proven their efficacy against the harmful effects of cathode-tube screens on the basis of rigorous scientific testing.
Scientists disagree about the impact of CRT radiation, although many suspect their existence.
It may be decades before a broad consensus develops. The general consensus at this time is the fact that if there is an impact on people from CRTs, it decreases with distance to become practically innocuous when reaching the equivalent of 8 times the diagonal of the screen. Whether these tests results may be used to infer with certainty human reactions to CRTs must await further studies and clinical research. The application of animal tests results to human health is not perfect. SEIC's laboratory is qualified ISO 9001 for reseaarch, development and production.
