Lung Diseases

Lung Diseases are a type negative player property given by special hazards added by Nuclear Tech Mod. These properties, like Radiation, can be incremented by held items and blocks as well as invisible gas/particle blocks. Unlike radiation, there is no exposure based purely on chunk or line of sight AoE.

Mesothelioma
Mesothelioma is a disease caused by prolonged inhalation of asbestos particles. Technically, it's a counter, adding 1 per asbestos sheet and 3 per asbestos powder in inventory a tick, up to 60*60*20 (72000). Once that limit is reached, the player will die with an unique death message: "Player was entitled to a financial compensation".

Mesothelioma can be prevented by wearing a gas mask with a filter having a Particulates trait (Gas Mask filter and Gas Mask Combo filter) and can be reset using SiOX Cancer Medication.

Black Lung
Black Lung, or silicosis, is another disease added by Nuclear Tech Mod. Upon mining a coal ore, Coal Dust is spawned, which can and will massacre your lungs.

Like mesothelioma, Black Lung is a counter to 72000. Unlike mesothelioma, it gives status effects, such as Weakness and causes you to cough blood and soot at higher levels. If the counter is less than 25% full, it decreases by 1 every tick.

A small pile of coal will add 1 to that counter a tick. An item of Coal Powder will add 9, however you won't get more than 90 a tick from them.

Gas masks having an Airborne Particles trait (also including the trench mask) will protect you from coal dust.

Using SiOX Cancer Medication will reset the disease to 25%, from which it will heal in around ten minutes.

Trivia

 * In real life, there is no real cure or even proper treatment for either disease except for preventing exposure in the first place.
