Dangers Of Plastic Containers I Have 500 G Of Potassium Hydroxide In A Plastic Container?Is There Any Radiation Hazard?

I have 500 g of potassium hydroxide in a plastic container?Is there any radiation hazard? - dangers of plastic containers

I found that it decays 0.0118% of the K40 (radioactive), potassium, or 0,06 to 60 mg gr in 500 K40 by beta emissions (89.3%). Is there a danger of radiation? What am I in a metal container? 40 K, the half-life = 1.28 * (10 9) years.
