Will you measure radioactivity in snow pak?

Given that you say rain concentrates the radionuclides, I imagine that snow would concentrate them even more? If this is correct then given that CA is dependent on a lot of its water from the snow in the Sierra's do you think it is worth measuring for levels of radioactivity in our snow pak to inform people of what we may expect to be drinking once the snow melts?

Will regular tap filters (e.g. PUR) remove some of these radionuclides?
