Officials involved with the cleanup are well aware of the drawbacks to these approaches: huge amounts of radioactive waste that no one wants to store long-term; immense investments of money, labor, and time; damage to wildlife habitat and soil fertility; increased erosion on scraped-bare hillsides; and intrusion by people and machinery into every area scheduled for remediation.
Bifunctional chelates offer a general approach for the linking of radioactive metal cations to macromolecules.
Leakage limits are specified using a conservative approach, which assumes escape of radioactive cover gas with fission products across the seals in bypass and permeation modes and possibility of sodium frost deposition in sealed gaps because of permeation leakage of inflation gas.
In February 2009, the atomic agency called for harmonizing the regulatory approaches toward the issue of radioactive materials turning up in scrapyards — a step yet to be taken.
Deep geological disposal facilities (GDF) proposed by US and European waste management organisations employ an engineered multibarrier approach to retard the release of radioactive species from the waste in quantities that could be detrimental to life and the environment.
[Huffington Post] A shipment of radioactive waste approaches its destination in Germany after a five-day trip from France during which the police clashed with antinuclear protesters.
Such a cavalier approach to deliberately releasing huge quantities of radioactive toxic poisons into an uncontrolled maritime environment is evidently unethical - and was known to be so at the time.
A similar approach was taken in the electrochemical preparation of radioactive iodinated parathyroid hormone [16].
However, these approaches have limitations such as time consuming, use of radioactive elements, poor reproducibility, and/or discriminatory power [ 25, 26].
Dr. Bart Barlogie, an expert on myeloma at the University of Arkansas and a consultant to Human Genome Sciences, said the idea of radioactive BLyS was "a very rational approach and technically feasible, and I look forward to seeing it evaluated".
