Hellooooooo!!!! What did you not understand about short half life = 
dangerous and really long half life not to worry???

>> Medical waste is NOT the problem.

>> "Reactor waste remains hazardous for a very long time. Most medical waste
>> from treatment and diagnosis is hazardous for a very short time. Research
>> and industrial waste can contain small amounts of some long-lived
>> radioactive materials.
>>
>> Among the radioactive elements commonly found in nuclear reactor
>> "low-level" waste are: Tritium, with a half-life of 12 years and a
>> hazardous life of 120-240 years; Iodine-131, half-life of 8 days,
>> hazardous life of 80-160 days; Strontium-90, half life of 28 years,
>> hazardous life of 280-560 years; Nickel-59, half life of 76,000 years,
>> hazardous life of 760,000-1,520,000 years, and Iodine-129, half-life of
>> sixteen million years, hazardous life of160-320 million years.
>>
>> By contrast, common medical waste elements include Technetium-99m, with a
>> half-life of 6 hours and a hazardous life of 2.5-5 days; Galium-67,
>> half-life of 78 hours and hazardous life of 1-2 months; and Iodine-131,
>> with its half-life of 8 days and hazardous life of 80-160 days.
>>
>> The vast majority of medical waste is hazardous for less than 8 months.
>> Yet, it is in the same category as reactor waste that will be hazardous
>> for hundreds of thousands to millions of years.
>>
>> Clearly, the definition of "low-level radioactive waste" must be changed.
>> It would make sense to redefine the more concentrated and/or longer-lived
>> waste as high-level. Active recontainerization and operational control
>> must be provided for the entire hazardous life of the waste, yet the NRC
>> requires only 100 years of passive institutional control. Thus, waste
>> hazardous longer than 100 years could be forgotten. Retrievability is
>> essential. "
