With an equatorial radius of 1195 km, Pluto has a circumference of about 7500 km but is only rotating at about 47 km/hr, which makes the day on Pluto about 160 Earth hours long. However, solar radiation does not appreciably heat its surface, which has an average temperature of 44°K (−230 °C).
If an electron moves from a lower energy level to a higher energy level, it absorbs energy. This energy is typically in the form of electromagnetic radiation or photons.

To find the temperature of Pluto based on the wavelength of maximum intensity (λ_max) of emitted infrared radiation, we can use Wien's Displacement Law, which states that λmax is inversely proportional to temperature (T). The formula is ( T = \frac{b}{\lambda{max}} ), where ( b ) is Wien's displacement constant (approximately 2898 μm·K). Converting 75000 nm to micrometers gives 75 μm, so ( T = \frac{2898}{75} \approx 38.64 ) K. Therefore, the temperature of Pluto is approximately 38.6 K.
The time it takes for the radiation level of strontium to drop to one-sixteenth of its original level can be determined using its half-life. For strontium-90, which has a half-life of about 29 years, it would take four half-lives for the radiation to decrease to one-sixteenth (since (1/2^4 = 1/16)). Therefore, it would take approximately 116 years for the radiation level of strontium-90 to drop to one-sixteenth of its original level.
Theoretically, solar radiation reaches the edge of the universe and possibly beyond. So the answer is yes but in a tiny amount, the sun is very faint from Pluto but radiation reaches it. Places millions of light-years away, radiation wouldn't be detected, but would exist in a super tiny amount.

High-level-control fluoroscopy increases radiation dose to the patient.
It is potentially dangerous. The radiation level found in granite is enough to suppress the immune system, cause birth defects, and cause cancer. There are granite composite options which are not containing the level of radiation that is dangerous.
Gamma rays have the highest energy level among all forms of electromagnetic radiation.
The level of radiation emitted by a light bulb is very low and considered safe for everyday use.

Background radiation.
If you are given the "the total radiation" (e.g. 100 rads of radiation) and you are given another radiation level (e.g. 75 rads of radiation) and then you are asked: 'What is "the fraction of the total radiation?"', then you would answer "75/100".
Yes, radiation has the ability to penetrate through walls depending on the type and energy level of the radiation.
