Yes you can use SHIELD OF 7 RAYS or ALL CLEAR SERUM with VK to prevent or clear radiations.
VK is designed for auto healing to send energies for 30 min, if your home is affected by Earth’s electromagnetic radiations , you will have to use VK continuously.
You may switch off the phone and gadgets in the night, but you can’t stop Electromagnetic radiations from Earth when you are not requesting VK , especially during the sleeping hours.
Sir has done these experiments with VK. He found that as the SHIELD breaks, the Electromagnetic radiations from Earth will again pierce the place to give harmful effect.
So you can evaluate if VK is enough or you need a VIBBES SEEDER , which emits energy continuously when attuned by Sir for a specific address.
