Apparently it’s not a lab, merely a radioactive waste deposit she used during her research. It has no value and you can’t even get in because of radioactivity.
It’s supposed to be torn down to build a cancer and rare disease research center who would have a lot more value than this unsanitary building.

This is the best summary I could come up with:

The building was scheduled for demolition as part of a development project that also threatens lime and plane trees planted by the double Nobel prize-winning scientist.

On Friday afternoon, France’s culture minister, Rima Abdul Malak, said the demolition was being “suspended” after consultation with the Curie Institute that owns the property to “allow time to examine … any possible alternatives”.

She and her scientist husband, Pierre, were the first to separate polonium and radium from uranium, a discovery for which both received the Nobel prize for physics along with Henri Becquerel in 1903.

In March last year, Paris’s City Hall approved the institute’s application to demolish the pavilion, designed by Henri-Paul Nénot in 1914, decontaminate the site and construct a five-storey structure to enlarge the campus.

Stéphane Bern, a French journalist who specialises in royalty, and whom Macron tasked in 2017 with drawing up a list of little known gems of the country’s monuments and buildings, wants to save the pavilion, the destruction of which he said “would be a serious error”.

But at City Hall, the deputy mayor, Emmanuel Grégoire, defended the planned demolition, saying Curie had “never, never worked” in the Pavillon des Sources, which campaigners say is untrue.
